A Pilot Bus Voltage Rectification Method Based On Voltage Control Area

With the rapid development of power net, more and more monitored nodes should be control. Accordingly more nodes' voltage is out of delimitation.Therefor, traditional method using experience of the operator cannot fit for the requirement of power system. Accordingly, using graph theory and operating experience abroad for reference, It firstly brings forward a new method of voltage rectification which based on pilot bus with voltage control area In view of the weak coupling among every VCA (voltage control area),using decomposing method of multi critical value, it realizes the eliminating vinculum of every VCA. And then, the rectification starts by pilot bus voltage of every VCA. So the resolution of whole power net is diverted into calculating smaller sub-net. As a result ,it can reduce the dimension of the formula, advance the success of voltage rectification, and curtail the time for calculation.In actual system, using expert system every VCA is more reasonable in engineering. When we'll carry out voltage rectification, we consider that different control variables have different sensitivity. So the action of control facilities should be more reasonable. And it runs well in the real system.
