Detection and compensation device for ship power system

The detection and compensation device for the ship power system comprises a controller, and the controller is connected with a flow sensor, a pressure sensor and a speed measuring instrument through an AD converter so as to detect multiple operating parameters of the ship power system. The controller is further provided with a voltage stabilizer, and the voltage stabilizer is used for providing stable and lasting power supply voltage for the controller. A wireless transceiver is arranged on the controller, and the controller is connected with an upper computer through the wireless transceiver, so that wireless communication is established between the controller and the upper computer, and operation parameters are transmitted in time; the controller is provided with a timer, the timer is used for recording time nodes corresponding to detected operation parameters, the controller is further provided with a hydraulic compensation oil way, and the hydraulic compensation oil way is used for conducting power compen
