File: 841002203 M-6283 THREE-PHASE DIGITAL CAPACITOR BANK CONTROL SUGGESTED SPECIFICATIONS Pole-Top/Pad Mount Capacitor Bank Control, metering, and monitoring for the Capacitor Bank shall be provided by a microprocessor-based package. The microprocessor-based package shall be suitable for Pole-Top or Pad Mounted Capacitor Banks, as well as Single-Stage Substation Capacitor Banks operating in Non-Series configurations. The control shall have the following minimum functional and behavioral attributes: CONTROL FUNCTIONS The capacitor bank control shall include the following features and can be used for either pole-top or pad mounted capacitor banks as well as non-series, single-stage, substation banks where SCADA communications are desired. LOCAL AUTOMATIC CONTROL MODE The Control shall have the following selectable Local Automatic Capacitor Control Methods: Classic Voltage, Adaptive Voltage, VAr, and Current with settings appropriate to the method selected. Capacitor Control Local Automatic Overrides: Maximum / Minimum Voltage Limits, Temperature, and Time. CLOSE and OPEN timers shall be provided with selectable Definite or Inverse TimeDelays. Timer Types: Selectable as Integrating or Instant Reset CLOSE and OPEN Output Pulse Duration adjustments shall be provided. CLOSE and OPEN Warning delays shall be provided. A mandatory reclose delay shall be provided to permit capacitors to discharge before reclosing after a prior trip. A minimum time-between-operations timer shall be provided that begins timing when any operation completes and prevents the OPEN or CLOSE timer from beginning operation due to an out-of-band condition until the timer’s setting is reached. LOCAL MANUAL MODE Local Manual Mode of cap bank operation shall be indicated on the front panel when switched into Local/Manual by a technician or an operator, and shall not be able to be operated by remote SCADA or other host computer(s) to maintain the safety of the technician or operator. Locally, the technician shall be able to CLOSE or OPEN the cap bank with all safety timers non-defeatable. Delta Voltage calculations shall be enabled during Local/Manual operation to block a technician command that would cause the Maximum or Minimum Voltage Limits to be violated. Page 1 of 10 File: 841002203 CAPACITOR BANK CONTROL OPERATION Control Operating Characteristic: The capacitor bank-control shall have independent phaseswitching and the operating characteristic shall be configurable for classic voltage, adaptive voltage, VArs, or current. The control’s configurable operating characteristic shall employ definite as well as inverse timing and provide an adjustable bandwidth to optimize bank operation and eliminate unnecessary switching. The configurable operating characteristic shall allow time and/or temperature overrides. The selected operating characteristic shall have further user-configurable selections to refine its switching decision. SENSING MODES Single-Phase Selection: This option will allow the user to choose which phase; A, B or C is used as the controlling parameter. Once this is selected, the control will use that phase value in Classic voltage control mode or Autodaptive® mode to make decision on how to regulate the load voltage. The option is valid for all three methods of control namely Voltage, VArs and Current. Three-Phase Average/Total: If three-phase average is selected the measured value of all three phases shall be averaged and used as the Effective Bandcenter for operation and to make it’s open or close capacitor bank switching decisions. When the control uses the VAr control characteristic, the averaging shall be replaced by the total sum of the VArs of all three phases. The CT multiplier shall be assumed equal when the VAr control method is selected. In Control Mode Limits, the three-phase maximum and minimum voltage shall be used to evaluate userassigned voltage limit violations. CONTROL MODES Classic Voltage Control: Classic voltage control shall make its CLOSE and OPEN switching decisions based on Control Close and Open Voltage settings and measured Line Voltage conditions and Time and/or Temperature overrides when applied. The control Close and Open Voltage settings shall apply based on the setting of the Control Phase Selection. Voltage excursions beyond the set value for greater duration than the time-delay will result in appropriate control operation on the affected phase. Adaptive Voltage Control: Adaptive voltage control shall contain two control methods, Fixed or Average. The Fixed method shall provide means to establish a bandcenter setting for each phase that the control uses for comparison to measured voltage to make CLOSE or OPEN capacitor bank switching decisions on the affected phase. The Average method shall monitor each phase independently and develop an Effective Bandcenter based on a long-term average of the input voltage on that phase for comparison to measured voltage to make CLOSE or OPEN switching decisions for the capacitor bank on the affected phase. VAr Control: VAr control shall make its CLOSE and OPEN switching decisions based on Control Open and Close VAr settings compared to Line VAr conditions. The control shall monitor each phase, and independently switch individual phase capacitor banks based on the individual phase VArs. A single pair of Control Open and Close Time settings shall apply to all three phases and VAr excursions that exceed the time-delay setting shall result in control operation on the affected phase. When the control uses the VAr control method, the VAr load shall replace the averaging on each separate phase. The CT multiplier shall be assumed equal when the VAr control method is selected. In Control Mode Limits, the maximum and minimum voltage shall be used to evaluate user-assigned voltage limit violations. Autodaptive Voltage Control method employs an inverse timer and bandwidth to optimize bank operation, eliminating unnecessary switching, and allow application of Time and/or Temperature overrides. Page 2 of 10 File: 841002203 Automatic VAr Control Mode Option: This option allows the control to make its Open and Close switching decisions based on measured line VAr conditions and Time and/or Temperature overrides when applied. VAr excursions beyond the set value for greater duration than the time delay will result in appropriate control operation. In addition, the control shall offer the option for Line Post Current Sensor inputs to provide phase current measurement to the control. Current Control: Current control shall make its CLOSE and OPEN switching decisions based on Control Open and Close Current settings compared to Line Current conditions. The control shall monitor each phase, and independently switch individual phase capacitor banks based on the individual phase current. A single pair of Control Open and Close Time settings shall apply to all three phases and current excursions that exceed the time-delay setting shall result in control operation on the affected phase. All Control Methods shall provide a Definite time-delay or an Inverse time-delay allowing faster response for larger excursions while eliminating unnecessary switching. All Control Methods shall provide a standard Instant Timer Reset or alternatively, an Integrating Timer Reset to facilitate bringing the controlled parameter solidly back in band. SCADA REMOTE MANUAL CONTROL MODE: SCADA Remote Manual Mode: The IVVC algorithm residing at the Master Control Center of the SCADA computer or other Host computer may use Remote Manual Mode for control. The control shall be capable of operating from SCADA signals received through wired or wireless communications media to command bank switches for OPEN and CLOSE operations. The cap bank control shall maintain an Overvoltage and Undervoltage Limit supervision to protect the “never to exceed” voltages set as standard by the utilities and SCADA shall be allowed to make OPEN and CLOSE commands as necessary when operating within those safety limits. The cap bank control shall provide a means to switch from Remote Mode to Automatic Mode if communications fail and continue to operate autonomously until communications are restored. The control shall provide contingency responses upon extended loss of communications. The capacitor bank control shall utilize a SCADA integrity monitor (SCADA Heartbeat) as well as additional means to monitor the on board communications module for loss of its own operation. Either failure or loss of communications from master or from slave shall trigger the cap bank to switch to Automatic operation. After communications are restored for a specified length of time, the cap bank control shall revert to SCADA Remote Manual Control Mode. This may be done automatically after a time-delay or as directed by SCADA Master. SCADA Remote Manual Mode - SCADA Heartbeat: A SCADA Heartbeat Remote Mode shall be provided as a means for the SCADA system to place the unit in Remote Operation to perform Open and Close operations as directed by a central control source. This mode shall have a timer, and as long as the Remote Timer setting in the control is refreshed by the SCADA system receiving a valid DNP 3.0 command, and before timing out, the control shall remain in Remote Manual Operation. If the delay times out, the control shall revert to Local Automatic Operation. The Local Automatic Operation shall switch back to Remote Manual Operation upon receipt of a valid DNP 3.0 command via SCADA. SCADA REMOTE MANAGEMENT OF LOCAL AUTOMATIC CONTROL MODE: SCADA Remote Management of Local Automatic Control Mode: The capacitor bank control shall have the capability to allow Remote SCADA Management of Local Automatic Capacitor Control. In this way, the Centralized Control can monitor cap bank controls allowing them to operate autonomously and only controlling them directly when emergencies arise. Management via SCADA or other Host computer capable of operating through wired or wireless communications media allows SCADA to effect control by either changing the local automatic control settings via analog signal or by sending binary commands for direct OPEN and CLOSE operations. Sending analog settings to the control and letting it operate based on its new Page 3 of 10 File: 841002203 marching orders instead of directing each open and close commands conserves bandwidth substantially and thereby minimizes the communications burden and total cost of operation. The control shall provide a SCADA Test Mode that blocks the unit’s physical outputs and removes the reclose delay, that normally prevents a Close operation for a minimum of five minutes after an OPEN. The control LEDs, front panel, and remote status indications shall still indicate bank operations as if the outputs were not blocked to allow user verification of settings, correct SCADA communications point mapping, and operation. INSTALLATION CONFIGURATION SETTINGS: VT Ratio Correction: The control shall provide VT ratio correction Phase Shift Compensation: The control shall provide phase shift compensation correction when in VAr or Current Control mode to correct for phase shifts normally encountered in line post sensors, and when current information sources are located on phases other than the measured voltage source. Operations Counter: The control shall provide a software counter that increments by a selectable X or 2X count for either a CLOSE or an OPEN operation. Re-settable Operations Counter: The control shall provide a second software counter similar to the operations counter that may be reset by the user. COMMUNICATIONS The communication ports shall provide access to all features, including metering, software updates, and programming of all functions. This shall be accomplished using a modem or direct serial connection from any PC-compatible personal computer running the control’s Communications Software package or via SCADA communications software. Communications Ports: Communication ports shall be optionally available in the following forms: Ethernet 10/100 Mbps through a copper RJ-45 connection (100 Base-T) Ethernet 100Mbps Fiber Optic with ST connectors (100 Base-FX) Serial Ports with RS-485, ST or V-Pin Fiber Optics, or RS-232 Protocols: The control shall support the following standard protocols: DNP3.0 and MODBUS. The USB port shall utilize MODBUS for local interface communications. The Ethernet port supports DNP 3.0, MODBUS, and IEC 61850 protocols over TCP/IP.

The eight sockets shall be capable of supporting Modbus and DNP over TCP/IP and up to five of the eight sockets shall be capable of supporting DNP 3.0. This requirement allows users simultaneous remote access to the control via the same physical Ethernet port to view/change settings or retrieve data, without affecting the SCADA communications. Full DNP Implementation The control shall provide full DNP implementation to support both report-by-exception and unsolicited reporting within DNP 3.0 to aid in the reduction of bandwidth requirements. The control shall also provide DNP File Transfer to permit the recovery of data logs and triggered events, oscillography, and device discovery to facilitate setting up the integrated system. In serial communication, the control shall have DNP addressing capability that allows networking of multiple controls. The DNP implementation shall support the pre-defined global addresses within DNP 3.0 and allow the user to define two additional global addresses. Each control shall be able to be assigned a Device Address, Feeder Address, and Substation Address ranging from 1 to 65519. The control shall support broadcast commands from the master to all controls on the network in order to allow some or all controls to act on one command at the same time. This capability reduces bandwidth and is critical for rapid response to changing system requirements with settings changes in multiple controls in selected zones. The control shall provide a configuration program that allows any point to be mapped into any DNP location and allows dummy filler points to be added to facilitate interoperability by replicating legacy vendor pointmaps to SCADA. This program shall also allow for individual point dead-banding and individual point assignments into Class 1, 2, or 3. Cyber Security The control shall provide the following information security mechanisms when operating within DNP: Permit multiple master source-address authentications, source-address validation, and multilevel access codes logged with date and time, with DNP authentication using FIPS 180-2 Secure Hash Standard (SHA-1) Full compliance with DNP 3.0 user group and IEC 62351-5 requirements, including all settings and configuration options Require password protected access to the control functions and maintain an audit log in compliance with NERC CIP standards Storage of 30 unique passwords in each control for user login via serial port, USB, modem, TCP/IP, or a password-keyed SD card, and include time-out and expiration features The ability to disable ports and services not required for normal or emergency services Enclosure intrusion detection device that asserts a SCADA alarm and triggers a temporary blocking signal to the control’s functions Bluetooth® The control shall have an option for Bluetooth® capability to enable 128-bit wireless encrypted access to the control that allows the user to configure the control, read status and metering values, as well as change set points.

A Voltage or Current THD Measurement exceeds its associated THD Trip pickup setting for the duration of the THD Trip time-delay 2. The control trips the bank and locks out 3. The Voltage or Current THD measurement drops below the THD Lockout Reset Setting as soon as the Trip occurs (within one second) 4. The THD Lockout Reset-Delay times out and the Lockout resets Maximum THD Lockout/Reset Operations: The control shall have a Maximum THD Lockout/Reset Operations setting to limit the maximum number of Trip and Lockout/Reset Operations allowed within a time-period specified by a Maximum Time for THD Lockout/Reset Operations before the control permanently locks out and requires a user reset, either locally or remotely, to continue operation. Settings Profiles and Triggers: The control shall provide up to eight settings profiles programmable in the control that can be initiated based on Time, Temperature, Loss of Communications, Reverse Power, or from SCADA. This feature shall allow the user the flexibility to customize the operation of the control based on many different operational factors while minimizing communications bandwidth.
