Control system

A control system that is applied to a power system, the power system comprising:

• a rotating electrical machine;
• a first electrical power storage unit and a second electrical power storage unit connected in parallel with the rotating electrical machine;
• and
• a switch provided closer to the second electrical power storage unit on an electrical path between the first electrical power storage unit and the second electrical power storage unit than a point of connection with the rotating electrical machine is,
• the control system includes:
• a first control device that controls charging/discharging of the second electrical power storage unit by opening/closing the switch;
• and
• a second control device that controls actuation of power generation and power running of the rotating electrical machine, the first control device and the second control device being able to transmit and receive signals to and from a third control device using a signal transmission section, the third control device being configured to perform an overall management to the control devices and transmit a command signal to the first control device in response to a reception signal from the second control device, wherein
• the second control device transmits, to the first control device and the third control device, a rotating electrical machine signal includes at least one of control information and abnormality information about the rotating electrical machine, and
• the first control device includes a function of controlling opening/closing of the switch on the basis of an open/close command signal about opening/closing of the switch transmitted from the third control device in response to the rotating electrical machine signal, and a function of controlling opening/closing of the switch on the basis of the rotating electrical machine signal transmitted from the second control device.
