牵引变电所微机并补保护动作行为对策研究

Study on the Actional Countermeasures on Micro-processor Protection of Shunt Capacitance Compensation System in Traction Substation

牵引变电所并联电容补偿装置(以下简称并补)是牵引供电系统中重要的电气设备,它的安全运行直接关系到电气化铁道安全稳定的工作,对牵引变电所微机并补保护动作可靠性要求相当高。在对牵引变电所微机并补保护动作行为统计分析的基础上,得到微机并补保护不正确动作的原因,并提出相应的解决对策,用以提高微机并补保护的可靠性,以达到牵引供电系统安全、稳定的向电力机车供电。

Shunt capacitance compensation system in traction substation is important constituent in traction power supply system.It＇s safe operation is directly related to electrification railway can work with safe and stable,micro-processor protection action of shunt capacitance compensation system in traction substation reliability requirement is quite high.On the basis of actional statistics and analysis on micro-processor protection of shunt capacitance compensation system in traction substation,failure reasons of micro-processor protection of shunt capacitance compensation system are received in traction substation,as to propose appropriate countermeasures,improving micro-processor protection＇s the reliability,thus provide electric locomotive with safe and stable traction power supply system.
