| Abstract: | The closing of the zero-crossing point of voltage in smart substation is studied, different phase-selection switching schemes in smart substation are proposed. The new method is discussed in detail from four aspects, namely, the receiving of sampling value packet, phase-selection switching calculation, parameter configuration of phase-selection switching and the switching on. The design of hardware is developed with the new intelligent terminal platform, and the verification test is made. The result of test shows that this method can meet requirements and provide reference for engineering application. This work is supported by State Grid Corporation of China. |
