1.灵敏度是指以状态变量表征的系统运行状况对控制变量和扰动变量的变化敏感程度，灵敏度分析是专家系统辅助决策不可缺少的手段。当不同变电站的电容器进行投切和有载变压器分接档位进行调节时，对受影响各节点电压及全网网损进行灵敏度分析，为了控制的正确性，必须知道节点无功变化对电网中节点电压的灵敏度。对于无功优化问题，必须求得电网中节点无功变化对系统有功网损的灵敏度系数，选灵敏度较高的节点作为无功补偿的候选投切点，从而尽可能从降低线损的角度来控制设备动作情况。
2全网动态电压无功控制决策
根据实时的SCADA系统采集数据，动态决策衡水电网调压设备和无功设备的调节，以实现电网电压无功优化运行的目的。
3全网无功优化补偿功能
当衡水电网内各级变电站电压处在合格范围内，控制本级电网内无功功率流向合理，达到无功功率分层就地平衡，提高受电功率因数。依据衡水电网对电压、无功变化的需要，计算决定同电压等级不同变电站电容器组、同变电站不同容量电容器组谁优先投入。
4全网电压优化调节功能

建议你雅信翻译，雅信是专业翻译软件，而且最主要是雅信里分专业了，比在线翻译的准确很多，而且根据不同的专业，单词翻译出来是不一样的。网上搜索一下雅信翻译就可以看到不少~~

1. Sensitivity refers to the state variables characterized the operation of the system of control variables and the changes in disturbance variable degree of sensitivity, sensitivity analysis to support decision-making expert system is an indispensable tool. When the capacitor different substation and a switching transformer-load stalls are adjusted, the affected nodes and the voltage loss for the entire network sensitivity analysis, in order to control the accuracy, we must know node reactive changes in the power grid Node voltage sensitivity. For reactive power optimization problem, we must seek reactive power grid nodes in the system changes meritorious loss of sensitivity coefficient, the higher sensitivity of the election of nodes as reactive power compensation for the candidate cut-off point, as far as possible, so as to reduce line losses from the point of view Control equipment in acti
