VOLTAGE AND REACTIVE POWER AUTOMATIC CONTROL SYSTEM BASED ON SCADA IN POWER SYSTEM
Ies Lab · Dianli xitong zidonghua · 2003
An applied expert system for voltage and reactive power automation monitoring based on SCADA model is proposed. This system expands the function of SCADA system, synthetically applies abundant information that is offered by the main station to the disposal of preventing error and unified consideration of senior and junior substation. It needs mutual harmony of standards, period of time and limit value, to accommodate the development trend of power system automation. The basic principles, schemes, characteristics and the problem in practical application of the power system design are introduced in detail. The operation results proved its distinct effect to improve the voltage quality.
