Abstract: The Static Start-up Control Technology for gas-steam combined cycle 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 that operates over a wide speed range, including zero speed, is presented also. Based on Real Time Digital Simulator (RTDS), the simulation model of Static Start-up Control Technology for gas-steam combined cycle unit was developed. Control algorithm of Static Start-up and its mathematical model is discussed in detail. Test results show that Units real rotation speed tracking for a given curve, and the Static Start-up of gas-steam combined cycle unit is realized. Then it is proved that the control strategy is a better control strategy for Static Start-up Control to gas-steam combined cycle unit.
