The Research And Design Of Automatic Voltage Control System Of San Menxia Regional Grid

Any kind of product has its quality indicators, electric power provided by power system for the majority of electricity customers, also has its quality indicators. Only if the indicators of power that sent to customers, are in line with the provisions of the quality indicators, the power can achieve the best benefits. Voltage, frequency and waveform are the three elements of national standards for power quality. The power system voltage control and reactive power optimization is of the most value according to voltage quality control. It’s related either power quality to meet various customers’demand of reactive power, or make the supply voltage at a stable qualified range. What’more, it’s a very effective measure for power supply enterprise’s internal potential,to response the requirements of energy saving and environmental protection, to reduce the loss of the line (network), to improve power efficient and economical operation. In this paper, we get the data model of the AVC system reactive power planning, optimization algorithms and flow calculation methods, calculation parameters need to input, Multi-Agent based collaboration technologies in dispatch center or the AVC system of centralized control station, by analysis the actual situation of the national grid San Menxia the power company grid. Then we solve the problem of coordination between the AVC control system, design the AVC system of San Menxia regional grid, list function modules of the system and the following specific management measures for system operation and maintenance.The voltage control and reactive power optimization system of San Menxia grid after implementation, is of not only the functions of online analysis and automated control, but also real value. The development and implementation of the system can greatly improve the San Menxia grid’s unreasonable reactive power management status, reduce the labor intensity of the tone value manual control, provide advanced technical means for the San Menxia grid’s voltage and reactive power optimization control and for running with security, stability, economic and efficiency.
