Yonghui Sun · Journal of Hohai University · 2012
The necessity and importance of leading phase operation of multi-generators are described.The key issues and current status of research on leading phase operation of multi-generators are analyzed and discussed. Based on theoretical analysis and field tests of leading phase operation of a single generator,the power system stability,voltage regulation,coordinated leading phase,and depth optimization of leading phase operation of multi-generators are analyzed.Advice for carrying out leading phase operation of multi-generators is given.Important topics and future work related to the research are pointed out.The results show that the leading phase operation of multi-generators has a better voltage regulation effect compared with that of the single generator,but can reduce the stability margin of the whole power system to a certain degree.Within a certain reactive-power regulation range,to improve the transient stability of the whole power system,it is better to arrange multi-generators than to arrange a single generator for leading phase operation.
