漳州電網(wǎng)自動電壓控制AVC系統(tǒng)的實現(xiàn)與應(yīng)用研究
[Abstract]:One of the basic criteria of voltage quality is that the voltage level on the user side is close to the rating value and the reactive power in the power grid is balanced on the spot. Substations play an important role in several major components of the power system. In the operation of substation equipment, the voltage and reactive power can be adjusted by changing the tap-changer position and switching the shunt capacitor bank of the on-load voltage-regulating transformer to achieve the purpose of regulating the voltage and reactive power. These methods can improve the qualified rate of voltage, reduce the reactive power loss and reduce the network loss, so that the power network can not only meet the power supply quality, but also can operate economically. Therefore, substation voltage and reactive power control has a very important significance and role. At present, the nine-zone diagram and its improved sixteen-zone algorithm are the most commonly used in reactive power and voltage control, so that the secondary voltage of transformer is located in the qualified area. The current dispatching automation technology and management methods are undergoing tremendous changes. As the latest automation of the three major technologies of regulation and control integration technology, county integration technology, intelligent power distribution technology in Fujian cities and cities around the company to carry out the construction in an orderly manner. In this context, the problems encountered by the AVC system in the control of integrated construction engineering need to be studied and solved, and the parameters are optimized according to the actual situation. At the same time, it is necessary to compare and select all kinds of implementation schemes in the process of AVC deployment, and to improve the operating effect of reactive power control system. The object of this paper is the AVC function of the data acquisition and monitoring system IES600, which is being constructed in Zhangzhou, and the function of the system is set according to the practical operation experience. In order to solve the problem of reducing adjustment failure in the case of too many AVC regulation instructions, the limit of action times and continuous action delay of capacitor and transformer tap in one day, as well as the screening of blocking signal, are studied in order to solve the problem of reducing regulation failure in the case of excessive AVC regulation instructions. From the choice of system mode, structure design, risk solving and so on, this paper compares and analyzes the different technical schemes that appear in the process of establishing AVC system under the mode of integration of prefecture and county, and expounds how to realize the function of AVC under the integrated EMS system of prefecture and county. And the remote control command sending mode of parallel remote control is put forward. Finally, referring to the experience of applying load forecasting method to AVC system at home and abroad, this paper discusses how to introduce the data of electricity meter reading system, which is widely used in the existing dispatching system, to make relevant calculation and make the load forecasting curve. The results of load forecasting are introduced to guide the substation capacitor and transformer tap-changers, which are overloaded or regulated frequently, so that when the load fluctuates, the frequent action of the device can be minimized, and the network loss can be optimized. The purpose of ensuring the safe and economical operation of power system.
