<p>PURPOSE:To reduce labor required for work by automating work, in which data are set to an exciter on the basis of an overexcitation limiting curve and a low excitation limiting curve, by using an electronic computer. CONSTITUTION:Data, such as the rated output, rated frequency, short-citcuit ratio, etc. of a generator are inputted. Rated reactive power 8 and the radius of a rotor-winding temperature limiting curve 1 are calculated, and the rated power-factor angle of the generator and the circular angle of the curve 1 are computed. The rotor-winding temperature limiting curve 1, a startor-winding temperature limiting curve 2, a stator-core temperature limiting curve 3, an overexcitation limiting curve 4 and a low excitation limiting curve 5 are calculated on the basis of these data. Data computed at that time are set to an excitation controller as a limiting value.</p> |
