Abstract：The large equipment electrical units include motor and power equipments ,voltage regulator control of electri‐cal units is the key to guarantee the stability of electric system .The principle and hardware implementation of recovery and simulation of electrical units uninterrupted dynamic voltage design without distortion is researched .The traditional method u‐ses Delta inverter technology to design voltage compensation traditionally ,it considers more active one cycle control ,har‐monic suppression and realization of voltage compensation recovery area is feasible ,but the voltage compensation effect for large electrical the unit is not good .An electrical unit bidirectional inverter voltage compensation technology is proposed based on fuzzy PID control .The voltage compensation restorer is designed ,and the circuit design and control principle of Delta inverter are analyzed .The fuzzy PID control is used to achieve bi‐directional inverter voltage compensation ,and the bi‐directional inverter voltage compensation algorithm is obtained to improve electrical units .Simulation test results show that the technology can improve the power of electrical unit ,the discharge frequency of PID neurons can achieve optimum ,and it can suppress buffeting and static dynamic current ripple ,the system voltage is improved .
