In order to improve the shortcomings of short circuit current of traditional power grid, this paper presents a method based on compensation method for short circuit current calculation. In the algorithm, the compensating method is used to introduce the compensation current in the fault port, so as to simulate the influence of the node short circuit fault on the original network. The method uses the admittance matrix before the fault to solve the state of the network, without modifying the node admittance matrix, can solve the whole network. This method can save the time of the admittance matrix after solving the fault, and can calculate the short circuit faults of various types. The calculation speed is fast and the result is accurate and reliable, which can meet the requirements of large grid adjustment and optimization of short circuit current. The method can provide technical support for the analysis of short circuit current limiting strategy.
