摘要
为模拟保护的动作情况,搭建了三相暂态仿真软件TS3ph与继电保护仿真软件Electrocon CAPE之间的接口,研究不平衡故障有可能在暂态中造成的剧烈电压波动以及不平衡故障在现实继电保护下的暂态仿真情况。通过开展在三相不对称电网和三相设备不对称操作下的暂态仿真,解决了传统正序暂态稳定仿真模型无法真实反映非对称故障的问题。
In order to simulate protection action, this paper establishes the interface between the three-phase transient simu- lation software TS3ph and the relay protection simulation software Electrocon CAPE and studies potential severe voltage fluctuation caused by unbalanced load and transient simulation on unbalanced fault in current relay protection. By developing transient simulation in the three-phase asymmetrical power grid and asymmetrical operation of three-phase equipment, it has solved the problem of the traditional positive sequence transient stability simulation model failing in truly representing unbal- ance load.
