现代输配电系统存在经济性、设备老化、可靠性等问题。为了解决这些问题，需要对设备进行优化维护，并根据设备当前的性能来运行输配电系统。为了实现这些目的，智能电网管理系统（IGMS）被提出并正在研究其基本功能。本文采用蒙特卡罗方法按时间顺序模拟了输配电系统的故障模式，并通过非线性规划将输配电系统中故障发生的所有事件评估为成本。通过多次重复这些过程来计算预期的 T&D 成本。通过最小化预期输配电成本，定量得出断路器和变压器的最佳维护策略。
Modern T&D system has the issues about economical aspects, aged equipment, reliability etc. To solve these issues, equipment should be maintained optimally and the T&D system should be operated based on the present performance of equipment. For realization of these purposes, intelligent grid management system (IGMS) was proposed and its basic functions are being investigated. In this paper, failure modes of a T&D system were chronologically simulated using Monte Carlo method, and all events occurred by failures in a T&D system were evaluated as cost with nonlinear programming. The expected T&D cost was calculated by repeating these procedure many times. By minimizing the expected T&D cost, the most optimum maintenance strategies of circuit breakers and transformers were derived quantitatively.
