Solid State Transformer (SST) has many attractive characteristics, including power quality improvement and reactive power compensation. The paper investigates the topology and control schemes of SST, and discusses its flexibility and reliability for both grid and customers. A model of SST applied for distribution network is constructed, and simulation shows the SST with appropriate control scheme can provide excellent power supply during both steady-state and dynamic-state with varying load.

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 s7-200 PLC is designed. It plays an important role in improving the power supply , guaranteeing the quality of voltage, reducing the loss of rural power gid.
