Abstract

Abstract:

In order to deal with the problem of multi-state frequency stability at DC receiving end, this paper studied the variation of inertia time constant and static characteristic coefficient of equivalent machine with or without pumped storage power generation by using the performance indexes of transient, dynamic and static frequency stability, namely reciprocal of instantaneous change rate, damping ratio and reciprocal of static deviation. The influence of pumped storage power generation on transient, dynamic and static frequency stability was analyzed. The performance indexes of each state were obtained and compared with those before. Finally, the model was built for simulation. Through theoretical analysis, it is concluded that pumped storage power generation improves the transient, dynamic and static frequency stability of the DC receiving end power grid. The correctness of theoretical analysis was verified by numerical simulation. The research results provid an important theoretical basis for the influence of pumped storage power generation on the multi-state frequency stability of DC receiving end power grid.

Key words: pumped storage, DC access, temporary-dynamic-static frequency stability, performance index
