A method for multi-variable control of a permanent magnet doubly-fed generator set

Abstract

The application discloses a kind of permanent magnetization double-fed generator set multivariable control methods for high-temperature adiabatic compressed air energy storage system, it is related to power generation technology coordinated control technical field, to solve the problem of high input-output variable coupling degree and large system internal disturbance in the energy release control process of high-temperature adiabatic compressed air energy storage system, its technical scheme key points are to realize the variable-speed constant-frequency operation of energy release process by using the characteristics of permanent magnetization double-fed generator, to provide a larger turbine speed adjustment feasible region for the sliding pressure operation of energy release process, and to realize the decoupling between the generator internal rotor winding current frequency, turbine valve opening and output power, output frequency by BP neural network inverse model, to improve the flexibility and stability of the system.
