A method of controlling the output torque of the prime mover using a frequency generator

The present invention discloses a method for controlling the output torque of the prime mover generator frequency using the following steps: A: calculating the value of each unit's power rating PGi is set range of power adjustment of each unit, and determines the load adjustment Electric Load effect coefficient KLD value; B: the amount of calculation of each unit perturbation ΔPi; C: calculated for each unit power adjustment unit KGi; D: for each unit separately obtained according to the difference Δf PI calculation of the real system frequency f is the nominal frequency fN power adjustment amount of each unit ΔPGi, consider regulating effect electric load, to give (ΔPGi-ΔPi) ÷ KLD = Δf (5); E: rotor according to the equation of motion of each unit, of formula (5) step D obtained to give real-time output of the prime mover torque TMi respective units, the calculated output frequency TMi unit as an input to the respective control system. Frequency control method of the present invention is simple and reliable, can be realized in the FM frequency changes in the power system automation, rapid tracking system, saving labor costs and improve the reliability of the power system.
