The Zhangzhou Grid Automatic Voltage Control AVC System Implementation And Application Of Research

An index of voltage quality is qualified is the voltage level of the user side and no power grid values near the local equilibrium at rated.Substation plays an important role in the major part of the power system,commonly used in the substation equipment operation to change the tap stalls and shunt capacitors to achieve the purpose ofregulating voltage and idle work. These methods can improve the voltage qualification rate, reduce the reactive power loss, reduce the loss of power grid, which can meet the quality of power supply, but alsothe most economic operation. Therefore, the substation voltage reactive power control has no meaning and function of is very important. At present no reactive voltage control is most often used is the nine zone and sixteen zone improved algorithm, the secondary side of the transformer voltage is within a qualified area.The current scheduling automation technology and management modeis undergoing tremendous changes. As to carry out the construction ofregulation of new automation three technology integration technology,integrated technology, the county intelligent distribution technology isaround Fujian City, everything in good order and well arranged. In this context, study and solve met in the regulation of one construction engineering problems in practice need the AVC system according to the actual situation, parameters need to be optimized. At the same timethe need for various implementation schemes are compared in the county one AVC deployment process, and improve the operation effect of no power control system.The study object of this article is the IES600 control integration of data acquisition and monitoring system of Zhangzhou is under construction in the AVC function, from the actual operating experience of setting the system function, the capacitor and transformer tap limits the number ofactions in a day and continuous time delay, and screen locking signals,solve the adjustment instruction reducing regulation the failure problem of multiple cases in the AVC; from the system model with selection,structure design, there is the risk of solve the comparative analysis of thedifferent technical solutions in a county one mode in the process of AVC system, explains how to realize the integration of EMS system by AVC function, and put forward the parallel remote control command remote control sending mode finally, both at home and abroad; other area load forecasting method is applied to the AVC system experience, explore thequantity of electricity meter reading system is widely applied into the existing scheduling system of data related to computing, load forecasting curve, the load forecasting result, the heavy or frequent adjustment ofsubstation capacitor and transformer tap to guide its action, can generate fluctuations in load, reduce the frequent tripping device, to Optimize network loss, and ensure the safe and economic operation of power systems for the purpose of.
