Patent JP-S63229508-A (JP)
Title: Power converting device for solar power generation
Inventor: SAKATA SUEO
IPC: G05F1/67
Filed: 1987-03-19
Abstract: PURPOSE:To keep the DC voltage at an approximately fixed level and to avoid the deterioration of its availability by using a correction means which corrects the voltage control rate in response to the active power supplied to a power system. CONSTITUTION:A current transformer 17 detects a direct current Id outputted from a photovoltaic power generation array 1 and supplies it to a DC voltage correction circuit 18. The circuit 18 obtains the correction value (m) in response to the current Id. In this case, the gain K of the circuit 18 is set so that the value (m) is equal to 0.04K in a rated state when it is supposed that the resistance value of an interconnecting reactance X is set at 4% for example. An adder A2 adds the voltage control rate K obtained from a DC voltage reference setting part 13 to the value (m) and supplies a corrected control rate (K+m) to a voltage control circuit 11. Thus, it is possible to control an inverter 3 so that the DC voltage Vd is kept at a constant level even though the output value of the pulse width modulated signal M' outputted from the circuit 11 changes in response to the current Id.
