Title: Improvements in or relating to stability control of alternating current systems
IPC: H02P9/06
Filed: 1945-02-08
Abstract: 593,149. Automatic control systems for electricity supply systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 8, 1945, No. 3211. Convention date, Feb. 10, 1944. [Class 38 (iv)] In a system comprising a variable-speed alternator supplying an A.C. motor, an exciter for the alternator is itself excited by a control generator having two differential field windings, one excited'in dependence on alternator voltage per cycle and the other in dependence on alternator load. In a ship propulsion system, forward and after alternators A1, A2 driven by turbines T1, T2 having speed control means H1, H2, supply starboard propeller motors M1, M2 and port propeller motors M3, M4 through lines L1 and L2 respectively. Switches S1, S2, S3, D1, D2, D3, D4 permit various alternatormotor combinations and these switches together with motor reversing switches RS1, RS2 and the speed control means H1, H2 may be arranged at a common control station. The motors are of the wound rotor type having secondary resistances SR1-SR4. A generator AB, driven by a constant speed motor D and arranged to buck or boost the supply from a source D.C. to the field FA of alternator A1, has its field. energized from a generator AC, also driven by motor D and provided with opposed fields F1, F2 respectively energized through rectifiers from potential transformer VT, and current transformer CT, associated with line L1. By virtue of a large inductance F, field F is dependent on the ratio of voltage to frequency while field F2 is dependent on load current, the arrangement being such that alternator excitation decreases with rise of the former quantity and increases on rise of the latter. Response to load current is more effective at high motor speeds. Resistances R4 and R6 are manually adjusted to suit operating conditions. Alternator A2 has a similar system of stability control. Discharge resistances DR and 2DR are associated with switches FS and 2FS in the alternator field circuits. To reduce alternator heating when operating four motors from one alternator, a switch S6 or 2S6 is closed to reduce the resistance across transformer CT and thereby diminish its boosting action. Automatic operation of these switches by interlocking with switches S1, S2, S3 and interlocking to prevent interconnection of the alternators is referred to.
