Rural Facility Electric Power Quality Enhancement [PDF]

open access: yes, 1991
Electric power disturbances are known to be more prevalent in small, isolated power systems than in larger interconnected grids which service most of the United States. This fact has given rise to a growing concern about the relative merits of different

串联补偿装置用MOV工况分析及其关键技术的研究

open access: yesGaoya dianqi, 2014
结合串联补偿装置的工作原理,仔细分析了金属氧化物限压器(metal oxide varistor,MOV)的工况,比较了TCSC与FSC不同构成的串联补偿装置中MOV的特点,对MOV的过电压保护和控制措施进行了较深入的讨论、总结。对设计MOV的关键技术——保护水平、能量耐受和工频电压稳定性、电流分布、特殊的短路电流释放能力等进行了深入研究。笔者根据国内某一500 kV交流电力系统串补工程的招标技术要求,设计了复合外套和瓷外套不同结构的MOV,产品通过了中国电力科学研究院的型式试验,满足工程需要。

Comparison of Surge Voltage Reduction and Economic Efficiency of DC SSCBs According to MOV and RCD Snubber Combination

open access: yesIEEE Open Journal of the Industrial Electronics Society
Metal oxide varistor (MOV) is a nonlinear resistive element whose resistance decreases rapidly when the applied voltage exceeds a threshold value. A dc solid-state circuit breaker (SSCB) uses MOVs or MOV with resistor-capacitor-diode (RCD) snubber ...
