中文摘要:

针对目前10 kV电网中性点不接地方式存在的安全隐患以及老式消弧线圈的缺点,本文设计了一种基于DSP TMS320F2812的可控消弧线圈补偿装置,装置采用改进极值法在线测量接地电容电流,根据中性点位移电压识别电网运行状态,判断故障类型,采用晶闸管二次调容的方式实现动态调谐,本设计采用过补偿和全补偿相结合的控制策略。测试结果表明,该系统能实现电容电流的在线精确测量和接地电容电流自动补偿的功能,可靠性高,有良好的应用前景。

英文摘要:

A controllable arc suppression coil compensation device based on DSP TMS320F2812 is designed in the paper for the safe hidden trouble of neutral non-grounded way and the disadvantage of the old arc suppression coil in 10kV power grid at present. The improved extreme value method is used to measure the earthing capacitive current online, recognition of operating condition of power gird and fault type can be judged according to the neutral point displacement voltage, thyristor secondary capacitance-adjustable is used to achieve dynamic tuning, a control strategy combined over compensation with full compensation is used in this design. The result suggests that the system can realize functions such as accurate on-line measurement of capacitive current and automatic compensation for the earthing capacitive current, the device has high reliability and a good application prospect.
