Abstract

The short-circuit capacity is a key parameter required for power system operation and control. This paper proposes a method for measuring the short-circuit capacity of bus in power grid by the non-fault disturbance caused by switching shunt capacitors. The short-circuit capacity can be calculated accurately by the proposed measuring principle. Based on this, a prototype is developed for field testing and research. In this paper, it establishes models for substation bus measurements based on MATLAB/Simulink and RTDS. The simulation analysis of various situations shows that the measurement error of the results of this developed short-circuit capacity tester is less than 5%, which is easy to use technically.
