前言纵观整个电网的发展,电力系统的主要特点表现为以下两点:一是电网中在运行的电力设备的种类和数量均急速增长;二是高电压等级和大容量的电力设备在电网中应用也越来越广泛。可以预见,现有的运维策略,即定期试验检修,一方面将难以满足现代化企业对设备管理的需求;另一方面也难以根据设备运行状况进行差异化跟踪运维;同时,试验检修的周期一般不会太短,如500k V变压器停电试验周期为3年,这也在一定程度上限制了提前发现缺陷、避免缺陷扩大化、预防事故的可能性。为解决以上问题,本文根据“基于电网设备状态评价的风险防范管理体系”的基本原理,辅以广州供电局所
Foreword Looking at the development of the entire power grid, the main features of the power system are shown as follows: First, the types and quantities of power equipment running in the power grid are rapidly increasing; secondly, the power equipment with high voltage levels and large capacity is in the power grid The application is also more and more widely. It is foreseeable that the existing operation and maintenance strategy, that is, the regular test and maintenance, will not meet the requirements of modern enterprises for equipment management on the one hand, and it is also difficult to carry out differentiated tracking operation and maintenance according to the equipment operation status. Meanwhile, Generally not too short, such as 500k V transformer power failure test period of 3 years, which also to some extent limit the defects found in advance to avoid defects to enlarge and prevent the possibility of accidents. In order to solve the above problems, this article based on “based on the status of power grid equipment to prevent risk management system ” basic principle, supplemented by Guangzhou Power Supply Bureau
