A method for determining equipment to be maintained based on comprehensive risk assessment of power system

[摘要] With the development of on-line monitoring and condition-based maintenance, the optimization research of condition-based maintenance scheduling is getting more and more important. A reasonable maintenance strategy can save a lot of energy and reduce costs. This paper proposes a method to determine the equipment to be maintained, which is based on the comprehensive risk assessment of power system. First we build a mathematical model of maintenance based on comprehensive risk index. Then non-sequential Monte Carlo simulation and DC power flow optimization model are used to minimize the sum of failure risks and maintenance risks. Finally, the feasibility and validity of the proposed model is analyzed on the IEEE-RTS79 system.
