Based on the analysis of the principle of phase difference detection for marine power station's parallel operation set, a method for improving the accuracy of phase difference detection is presented. This method uses the interruption mode to reset and read the current count value of high speed counter to measure lead time and accurately calculate the time point of giving a sign of switching on. On the experimental platform of physical simulation system of marine power station, the phase difference detection device of marine power station is designed by choosing S7-1200 PLC as the core controller. Complete the design of peripheral hardware circuit, as well as PLC configuration and programming. The accuracy and reliability of phase difference detection are verified, after many experiments on the physical simulation experimental platform of marine power station.
