Automatic Voltage Control
... Ideal in unmanned substations, the AVC scheme runs independently to provide safe parallel operation of transformers. The AVC application recognizes all switchgear connected to reactors, busbars and transformers. It polls the switchgear connected to the secondary windings to select logical groups for ...

HVAC Design Criteria and Guidelines ELECTRIC HEATING COILS
... Determining the number of stages of electric heat requires consideration of the total ΔT of the heating coil and the degree of control required. For “good” space temperature control, the ΔT for each stage should be generally no more than 5ºF, though 10ºF per stage may be “adequate” for noncritical c ...

Distributed control system
A distributed control system (DCS) is a control system for a process or plant, wherein control elements are distributed throughout the system. This is in contrast to non-distributed systems, which use a single controller at a central location. In a DCS, a hierarchy of controllers is connected by communications networks for command and monitoring.Example scenarios where a DCS might be used include: Chemical plants Petrochemical (oil) and refineries Boiler controls and power plant systems Nuclear power plants Environmental control systems Water management systems Metallurgical process plants Pharmaceutical manufacturing Sugar refining plants Dry cargo and bulk oil carrier ships Formation control of multi-agent systems
