Abstract: PROBLEM TO BE SOLVED: To schedule start/stop of a generator in a short time by narrowing down the candidates of start/stop from the relation of two point per day, i.e., maximum and minimum demand points, thereby minimizing the processing for avoiding violation of restrictions. SOLUTION: Two time points, i.e., maximum and minimum power demand points P, N, are extracted in a day during schedule period and start/stop candidates of a generator are created at respective time points with reference to a schedule reduced to two time point per day. Start restrictions are then evaluated from the combination of candidates at maximum and minimum power demand time points. In this regard, violation of restrictions is detected by evaluating the relation of operation or stop of the generator at the maximum and minimum power demand points P, N. Since the processing for avoiding violation of restrictions can be minimized, start/stop schedule of the generator can be obtained in a short time.

Title: Control method for inverter output voltage
Inventor: HACHIRO TOMOYASU
IPC: H02P27/06
Filed: 1993-04-30
Abstract: PURPOSE:To suppress inrush currents to a motor during power recovery from an instantaneous power interruption by multiplying an output voltage command by a coefficient which becomes smaller than 1 in response to a drop in DC voltage by a DC voltagecoefficient conversion circuit after the DC voltage has dropped due to the instantaneous power interruption. CONSTITUTION:A DC voltage Vdc drops due to an instantaneous power interruption. A DC voltage-coefficient conversion circuit 31 outputs a coefficient which becomes smaller than 1 in response to a drop in the DC voltage Vdc, and an output voltage command V0 is multiplied by said coefficient through a cushion portion 32 and a multiplier 33. Because of this, the output voltage decreases in response to the drop of the DC voltage. When the power has been recovered, the DC voltage Vdc rises suddenly, so that the coefficient from the DC voltage- coefficient conversion circuit 31 approximates to 1 and, at this time, a coefficient output from the cushion portion 32 approximates to 1 with a constant time function. The output voltage command V0 is multiplied by said coefficient by means of the multiplier 33, so that the output voltage command V1 rises to a stationary value with a constant time function.
