The role of MOV, trigger gap, and by-pass circuit breaker was analyzed, and the measures for restricting over-voltage on capacitor bank and capacitor bank protection, as well as the operation sequence and control method for series compensation installation were put forward. 分析了金属氧化物变阻器(MOV)、触发间隙、旁路断路器的作用,提出了限制电容器组上的过电压,保护电容器组的措施,以及对串联补偿装置操作的顺序与控制方法。
The principal component analysis ( PCA) combined importance weight is used to evaluate control nodes 'comprehensive capability to alleviate overload on the section, and determine the operation sequence of control nodes. 为实施输电断面有功安全性保护而选择控制节点时,利用结合重要性权重的主成分分析法评价节点消除断面过载的综合能力并实施排序,以此获得控制节点操作序列。
The practical operation proves that the sequence logical control works fine and is reliable and the equipment runs normally. 实际运行证明,顺序逻辑控制正常可靠,设备运转正常。
Based on this, by combining the operation sequence of control in substation automation, a security communication system of remote control for substation automation is designed. 在此基础上,针对变电站远程控制的安全需求,结合变电站自动化控制操作的动作序列,设计了变电站自动化远程控制的安全通信体系。
By this method, the middle logic operation control process is omitted. The method is particularly suitable for complicated sequence program control as the programming is digitalized. 省去了中间逻辑运算控制环节,这对复杂的顺序程序控制尤为适应,使得顺序程序控制编程数据化。
