Aiming at the large error and simple test condition of traditional method for determining the unit leading-phase capability, a method for simulating the unit leading-phase capability of thermal power plant is proposed based on the static auxiliary power model. A modified static auxiliary power model is put forward, which applies the method of parameter identification based on the actual operating data of power plant. The auxiliary power model is built on PSD-BPA software platform to simulate the unit leading-phase depth in different operational conditions when the voltage limit of auxiliary power or the static stability limit of unit is reached. The measured data of a 1000 MW unit from June 2013 to June 2015 are applied to calculate its leading-phase capability. The simulative results are compared with the measured data of its leading-phase test, verifying the effectiveness and rationality of the proposed method.
