Error Calibration

Three-phase combined transformer has a large number of application to special energy metering in power grid, its performance is directly related to the accuracy of electric energy metering. So it is necessary to ensure its performance and accuracy. It rules that three-phase combined transformer should be calibrated with three-phase method, but most of metrology departments calibrate three-phase combined transformer in single-phase method. Based on the mechanism of the three-phase transformer, single-phase method and three-phase method had been compared on three-phase transformer experimental platform. The result shows that it would be large error when the three-phase transformers are calibrated with single-phase method. Three-phase transformer calibration should be operated with three-phase method.

With the extensive development and use of new energy sources, it has become an urgent issue to solve the problem how to effectively use such energy sources. This paper designs a single-phase electric energy router (SPEER) whose main goal is to solve the problem of optimal operation of the home power system under a high penetration rate of new energy. First, a SPEER structure is presented which has an AC-DC hybrid form to meet the power requirements of all household electrical equipment. Compared with the existing structures, its structural design is more suitable for small-capacity systems, such as home power systems. Next, a reasonable, detailed, and feasible control scheme was designed for each part of the SPEER, so that it has the functions of plug and play, power routing, island detection, and synchronous grid connection, and a seamless coordination management scheme between subsystems was designed. Complete functions make it more intelligent in response to various conditions. Finally, the correctness of the designed SPEER and control strategy was verified by experiment.
