Abstract

653,994. Automatic control systems for electricity supply systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 1, 1948, No. 23028. [Class 38 (iv)] The load on two or more alternators is shared equally under the control of the normal voltage regulators for the alternators, by providing additional coils on the regulators excited from a closed balancing circuit supplied by seriesconnected rectifiers individually connected through current transformers in the output currents of their respective alternators; Fig. 2, shows four alternators supplying a D.C. network through rectifiers 61 ... 91, voltage regulations being effected by known field regulators 63 ... 93. Equal load-sharing is accomplished by the provision of additional coils 64 ... 94 on the regulators, connected to a closed balancing circuit including rectifiers 65 ... 95 connected to output current transformers 62 ... 92. Under conditions of equal load-sharing, no p.d.s exist across the individual coils 64 . . . 94, but any unbalance causes excitation of the coils in such a manner that the voltages of the alternators are appropriately raised and lowered so as to restore balance. The system may also be applied to alternators supplying an A.C. network.
