Power System Reliability Analysis System Based on PSASP and Fault Enumeration Method and Applications

Power system reliability calculation is an important power system analysis method, which is always held in high regard by power system researchers and operators. In this paper, the probability parameters of power system components in various states can be calculated by Markov process based on the parameters of independent outage model and related outage model and Fault enumeration method is used to enumerate all possible faults and disturbances, and calculate the probability of various possible states. A power system reliability analysis system is developed based on PSASP. The application of the system shows that the system has perfect functions and friendly interface and can quickly calculate the technical indicators of power system reliability Evaluation system of the reliability technical indicators is complete, which can be used to evaluate the reliability of the power grid from various angles. The system can help electricity workers understand the weaknesses of power grid or load points in the actual operation of the grid in order to take appropriate measures to prevent accidents or minimize the impact of the accident. It can also provide scientific basis for decision making to workers considering the economy and reliability of power supply grid during making network planning in order to develop a rational power network planning.
