摘要:在電力系統(tǒng)發(fā)生的故障中，輸電線路的故障占了不少，因此提高輸電線路運行的可靠性對于保證電力系統(tǒng)穩(wěn)定運行有著重大意義。根據(jù)以前的電力系統(tǒng)運行經(jīng)驗可知輸電線路故障絕大多數(shù)是瞬時性的，那么此時如果能夠把斷開的線路重新合上，線路就能夠恢復(fù)正常供電。為此在電力系統(tǒng)中采用了自動重合閘裝置，在斷路器跳開以后，該裝置能夠?qū)⑵渲匦潞仙?。但是，傳統(tǒng)的自動重合閘在使用過程中存在著許多問題，傳統(tǒng)的自動重合閘裝置動作級數(shù)多，觸點工作不可靠，經(jīng)常發(fā)生拒動或者誤動。這里可以利用可編程控制器（簡稱PLC）所具有的優(yōu)點，通過硬件設(shè)計和軟件編程實現(xiàn)基于PLC的自動重合閘，該種自動重合閘抗干擾能力較強，具有很好的穩(wěn)定性。 關(guān)鍵詞 自動重合閘；可編程控制器；穩(wěn)定性
Abstract:Fault in power system, are mostly fault in transmission line, so how to improve the reliability of transmission line work, has become one of the important tasks in electric power system. That run by the experience of power system in the past, the overhead line fault is transient, so at this time if the broken line to close automatically, the power supply will be able to return to normal, reduce outage brought great loss. The automatic reclosing device in power system, when the circuit breaker tripping, the device can be re-closing. However, there exist many problems in the automatic reclosing of the traditional use of the process, the automatic reclosing device action most of the traditional contact adhesion, unreliable factors, often happen mis-operation or mal-operation. So we can use the improved PLC programmable controller to the traditional automatic reclosing, through a series of hardware design and software programming of automatic reclosing based on PLC, the automatic reclosing of strong anti-interference ability, reliable stability. Keywords auto reclosing programmable controller stability |
