Summary: | PROBLEM TO BE SOLVED: To constitute a control system of an auxiliary power plant with a digital system and provide with battery charge monitoring function and engine constant speed control function. SOLUTION: An auxiliary power plant comprises an engine 100, a generator 200, a control system 300 and a battery 600. The control system 300 comprises a rectifying part 320, a first classifying circuit 340, a smoothing circuit 360, a contactor 380, a main control part 420, an engine constant speed control part 440, an auxiliary battery 460, a DC voltage conversion part 480, a battery charge monitoring part 520, a control state display part 540 and a second classifying circuit 560. The main control part 420 of the control system 300 judges a signal inputted from each part of the control system 300 and transmits a control signal to each part to control the whole system. The engine constant speed control part 440 detects the rotating speed of the engine to perform constant speed control of the engine, and control signals from the main control part 420 is transmitted to the engine constant speed control part 440 so as to control on/off of the engine. |
