Analysis of a Static Start-up Control Strategy for Pumped Storage Power Plant Unit

Abstract A static start-up control strategy for pumped storage power plant unit is presented and the sensor less control to rotor position detecting is analyzed according to voltage and magnetism equations of ideal synchronous motor mathematics model. The simple-to-implement estimation technique of sensor less control to rotor position detecting in which operates over a wide speed range, including zero speed, is presented also. Control strategy of static start-up and its mathematical model is discussed in detail. Based on 500 kW synchronous motor, the test of static start- up control system for pumped storage power plant unit is developed. Test results show that pulse commutation, nature commutation and unit synchronous procedure of static start-up are realized. Then it is proved that the method presented in the paper is a practicable control strategy for static start-up control to pumped storage power plant.
