Operation safety analysis of substation main wiring based on new risk assessment model

The safe and stable operation of power system is an important guarantee to maintain the harmonious and stable development of society and improve people's living standard. Substation, as a key part of power system, plays an important role in collecting and distributing electric energy, and its operation condition determines the reliability of power supply and operation risk of regional grid. At present, the traditional evaluation model is often used to analyze the operation safety of substation main wiring. This model has certain limitations, and the evaluation results can not objectively reflect the real operation risk of substation and regional grid, so the results do not have enough reference value. Therefore, this paper firstly constructs the operation safety evaluation index system of power grid operation, and then improves the traditional risk assessment model of substation main wiring, forming a safety analysis method of substation main wiring operation based on the new risk assessment model. The results show that compared with the traditional risk model of substation main wiring, the model used in this paper considers a more comprehensive and scientific scope, and the evaluation results are more conservative, which provides a new idea for the operation risk assessment of substation main wiring.
