Abstract
967,964. Measuring electrically. BROWN, BOVERI & CO. Ltd. Aug. 16, 1961 [Aug. 18, 1960], No. 29540/61. Heading G1N. [Also in Divisions G3 and H2] The electrical angular position of a synchronous machine rotor with respect to the system voltage, i.e. load angle, is measured as a voltage by feeding the output of a pulse generator, mechanically driven from the synchronous machine, and the system voltage to a gating/inverting/ filter network. On no load, pulses 1 from the pulse generator which are aligned to correspond with the peaks of the system voltage 2 control the gating/inverting circuit to allow either the wave or the inverted wave to pass giving waveform 3, whose mean value at the filter output is zero. On load the pulses 4 are displaced in time by an amount proportional to the load angle, but the system waveform remains fixed, and after gating/ inverting waveform 5 is obtained whose mean value is now a voltage proportional to load angle. This measuring system may be used in a regulating circuit where oscillations of the rotor are damped out by varying the machine excitation (see Division H2).
