Abstract


Voltage power system is an important performance indicators, power quality is an important indicator. Good voltage level is not only safe and stable operation of the power system to ensure, but also to reduce power loss and improve the economic efficiency of power grid has very important significance. Automatic voltage control a unified power grid (Automatic Voltage Control, AVC) is to further improve the system voltage level, to ensure grid security, stability, quality, economy and effective measures. Since the 1980s, research and practice have become a hot spot in this area. Its obvious advantages, however, In fact, the complexity of the existing rather is due to voltage and reactive power nonlinear characteristics unique to their own. With the development of computer technology, communication technology and network technology, as well as power plants, substation automation popularity, the grid has been possible to achieve a unified AVC.According to the AVC System Research and Application of analysis to prove that the region is feasible at this stage of AVC. regional AVC technically more perfect, and with AVC provincial transfer control interface. This issue needs based on the construction of Sichuan Provincial Power Company AVC system, building AVC master and sub-stations and the main station to achieve AVC, AVC sub-county transfer station system integration, AVC system into the closed-loop control, the control station of the implementation methods are:Local mobilization of AVC System -> County transfer AVC System -> County transferred dispatching automation -> integrated automation device control transformer on-load tap changer and capacitor means to achieve control.After completion of the system put into use in Yibin Power Administration, test results show that the AVC system flexibility to adapt to changes in the grid a reasonable way of reactive power and voltage regulation, which is VQC (Voltage Quality Control is an integrated automatic voltage and reactive power control) device not available. AVC investment, slow down the system the problem of excessive voltage ripple.
