摘要

自1975年以来，特高压电网系统的保护继电器都是用电子元件建造的。经过30年的服役，一些部件出现了老化问题:失效模式，当设计完成时未知，导致电网系统发生一些事故。提出了一种控制这些风险的组织方法。对保护的功能链进行了分析，其中跳闸对数量和功能的影响最大)，以便将主部件故障与其对电网系统运行的影响联系起来。提出了简单的测量方法，以及引起这些老化现象的研究方法。

Getting under control the ageing of static protection relays

Protection relays of the Ultra High Voltage grid systems were built with electronic components since the years 1975. Afer 30 years in service, some components present ageing problems : the failure modes, unknown when the design has been done, caused some incidents on the grid systems. An organization method is proposed to put under control these risks. The analyses of the functional chains were carried out on protections, the trips of which have the greatest impacts f l y the number and functionality), in order to connect the principal component failures with their consequences on grid system operation. Simple measurements are proposed, as well as research ways on the phenomena causing these ageings.
