ABSTRACT

Leading phase operation of generator is an effective method for the control and regulation of voltage and reactive power of power system. The ability of voltage regulation for key buses by control of generator is presented in this paper. The PSD-BPA software - Power System Analysis Software Package (PSD-BPA) is introduced firstly. The management database for leading phase operation of generator is discussed. From the lagging phase operation to leading phase operation of generator, the change curves of voltage for main 500kV bus and 220kV bus are analyzed. The sensitivity on voltage regulation of each generator of leading phase operation is given. Based on the analysis of short circuit fault of power plant, the limit output power of leading phase operation of multi-generators is proposed. The leading phase operation of generator has many advantages, such as easy to operate, simple and feasible implement, and the actual operation is safe and reliable. The technique was worthy to be widely used.
