Aiming at the problems of unstable turbine load control and low operation efficiency under variable load condition,a control strategy based on BP-PID algorithm is proposed.A BP neu-ral network is constructed to adjust the PID control parameters to realize the purpose of improving the operational stability and operational efficiency of the turbine under variable load operation mode.Simulation tests show that the method can effectively improve the turbine operation efficiency and en-hance the unit operation stability Engineering practice shows that the turbine operation efficiency is improved by 1.538%after applying the control method.
