    Abstract:

    For the purpose of solving the unbalanced problem of power metering in the smart substation, a multidimensional field test technology is proposed for multiple bay electric energy metering in substation in view of the characteristics of digital multiple bay electric energy metering system is considered such as many links involved, blind areas in laboratory testing and lack of field test means . Firstly, the main reason of abnormal measurement is analyzed for the digital multiple bay. Then, a bay injection test is proposed on the basis of the wireless transmission and the implementation scheme and the key issues is described such as the distributed terminal synchronization, precise trigger of passive sampling and sampling curve fitting. Finally, the proposed scheme is verified by experiments. It is shown that the method could realize the error location and performance test of multiple bay electric energy under the condition of maintaining the integrity of the system and the field test ability of digital metrology specialty is improved.
