Abstract

In the present rural power grid reconstruction project, according to the problems of capacitor reactive power compensation in rural small substation. Take a small substation for instance, according to its operation and control method, set the criterion of the capacitor bank switching. A new high reliability, flexible reactive power compensation control device Based on S7-200PLC is designed. It plays an important role in improving the power supply, guaranteeing the quality of voltage, reducing the loss of rural power grid.
