The 12–pulse interphase transformers and the filter inductors are to be stacked two high, resulting in four interphase/filter reactor assemblies. It is preferred that all of this equipment be delivered 16 weeks after the purchase order is issued. We can consider longer delivery times if necessary. 1.1 Introduction The National High Magnetic Field Laboratory (NHMFL) has installed four 24-pulse rectifiers, also called power supplies. (Details of the power supply design can be found in a paper with the title “Design and Operation of a 40 MW Highly Stabilized Power Supply”. A copy of the paper is attached to these specifications.) Each 24-pulse rectifier consists of two parallel-connected 12-pulse rectifiers; and each 12-pulse rectifier consists of two parallel-connected 6-pulse rectifiers. All rectifiers are phase controlled. Parallel operation of two 6-pulse rectifiers is accomplished by means of an interphase transformer. In the existing system, the two unconventional interphase reactors (labeled interphase/filter reactors) between the two 12–pulse rectifiers of each power supply serve a dual function, providing reactance to the circulating current of the two 12-pulse converters and also providing the inductance for the series connected passive filter. All existing interphase transformers must be replaced because the rectifiers are being upgraded to higher voltage and current ratings. All new 6-pulse interphase transformers will be a direct physical replacement for the existing units, except for higher voltage and current ratings. The two unconventional 12-pulse interphase/filter reactors of each power supply will be replaced by one conventional 12-pulse interphase transformer and one separate filter reactor. The new 6–pulse interphase transformers will be installed in the same locations as the old units, therefore the physical dimensions of the new transformers can be only slightly larger than the existing transformers. The physical dimensions of the new conventional 12–pulse interphase transformers and separate filter inductors are less restricted but will be required to fit into the existing cabinets in the space presently occupied by the interphase/filter reactors. In each power supply, the 12-pulse interphase transformer must be mounted on top of the filter inductor. The 6–pulse interphase transformers are labeled IPT in Fig. 1 of the paper. As shown in Fig. 1 of the paper, there are two interphase transformers in each 24-pulse power supply and therefore eight altogether. Each interphase transformer is installed in the negative output of two paralleled, six-pulse rectifiers. Each interphase transformer is installed in a different cabinet, each of which houses one 12-pulse rectifier. The interphase 7 transformers are located on the floor under the two 6-pulse rectifiers as shown in Figure 1 below. The no-load voltage of each 6-pulse rectifier can reach 950 Vdc. In the existing system, there are also two unconventional 12-pulse interphase/filter reactors in each power supply. As is shown in Fig. 1 of the above mentioned paper, these units are connected to both the positive and negative terminal of each 12-pulse rectifier, labeled “Converter #1” and “Converter #2”. The units are labeled by their inductance values (46.5 μH). The physical construction of the units is in the form of an interphase transformer with the two 46.5 μH windings of the positive terminal of Converter #1 and #2 on one core and the two 46.5 μH windings of the negative terminal of Converter #1 and #2 on another core. To meet space requirements the two cores are stacked on top of each other. Interphase/Filter Reactor 6 - pulse Interphase Transformer Figure 1. Part of one power supply showing two 6-pulse rectifiers, one 6- pulse interphase transformer and one Interphase/filter reactor. This is the existing arrangement. 1.2 New Passive Filter Arrangement In the new system, the 12–pulse interphase/filter reactors will be replaced by a combination of a separate 12–pulse interphase transformer and a separate filter inductor. The system is being changed to this new arrangement in order to reduce circulating 8 currents between the 12–pulse converters while also maintaining an inductive component for the passive filter. The new passive filter arrangement is shown in Figure 2 of these specs. One input of the 12–pulse interphase transformer will be connected to the positive terminals of Converter #1, and the other input will be connected to the positive terminals of Converter #2. The output terminal of the interphase transformer will connect to the positive bus of the passive filter. The filter inductor will be a two terminal device connecting the outputs of the 6–pulse interphase transformers of Converter #1 and Converter #2 to the negative bus of the passive filter. The 12–pulse interphase transformer and the filter inductor must be stacked in order to fit into existing cabinets. Drawings of the cabinet dimensions can be provided by the NHMFL. Figure 2. New arrangement of the rectifiers and passive filter. 9 1.2 Mode of Operation The power supplies and with them the interphase transformers and filter reactors operate 15 hours per day, five days per week, though 22 hour, 7 day operation is possible. The power supplies operate on the average about two-thirds of the time in a transient mode and one-third in a steady-state, full power mode. In the transient mode the power supplies ramp up from zero power to full power in about one minute (or longer) and then ramp down to zero power during the next one minute (or more). The transient mode and the steady-state mode are scheduled in a completely arbitrary way. The fundamental frequency of the 6–pulse interphase transformer voltage in both modes of operation is 360 Hz. The voltage across the interphase transformer during the steadystate, full power mode is approximately triangular in shape with a peak voltage of 140 V. The maximum voltage across the 6–pulse interphase transformer occurs during the transient mode at zero average output voltage when the voltage shape is rectangular with peak amplitude of about 500 V. In the transient mode, the voltage shape of the 6–pulse interphase transformer voltage changes constantly between these two mentioned extremes. The fundamental frequency of the 12–pulse interphase transformer voltage in both modes of operation is 720 Hz. The voltage across this interphase transformer during the steadystate, full power mode is a square wave with a peak voltage of approximately 120 V. Under low output current conditions, the voltage across the 12–pulse interphase transformers is approximately triangular in shape with a peak voltage of 200 volts. In the transient mode, the voltage shape of the 12–pulse interphase transformer voltage changes constantly between these two mentioned extremes. All the reactors must be designed thermally for steady-state operation. 1.3 Interphase Transformer Current Imbalance The rectifier control system maintains a much closer current balance between rectifiers than is normally seen in industry. The 6–pulse interphase transformer should be designed for a maximum current imbalance of 200 amps DC at its input terminals. The 12–pulse interphase transformer should be designed for a maximum current imbalance of 100 amps DC at its input terminals. 10 2. 6-Pulse Interphase Transformer Specifications 2.1 General Number of units Type Number of terminals 2.2 Electrical Winding direction of coil halves Current rating of winding Current rating of center terminal Voltage between end terminals, normal operation worst case Voltage class of unit Frequency, normal operation Flux density DC resistance Copper losses Iron losses Inductance Inductance tolerance Voltage level above ground Winding to ground test voltage Symmetrical short circuit current for 150 ms Winding material Air gap Iron core shape Iron core material 2.3 Cooling Type Temperature rise Water flow 2.4 Environmental conditions Enclosure Elevation Ambient temperature 8 dry type, iron core 3, one at each end, one in electrical center; terminals must match existing layout.

NHMFL reserves the right to witness the tests, wherever they take place. 15 6. Reactor Warranty The reactors should be warranted for 12 months after being energized or 18 months after being delivered, whichever condition comes first.
