Abstract
A multi-node synchronous on-site test method, the method comprising: using GPS time as time reference, and conducting synchronous on-site tests on the devices to be tested and systems distributed at different places at an appointed time; controlling the synchronous phase control simulation devices distributed at multiple nodes via a synchronous test control center; within a uniform time section, synchronously outputting secondary side AC simulation signals, and simulating various actual operating conditions, thus achieving the detection of the monitoring and control performances of various dynamic monitoring and control systems, and ensuring the normal functions of the systems. The method of the present invention is able to conduct multi-node dynamic simulation test with synchronized GPS time, and achieves the detection of large-area multi-node monitoring and control systems. The present invention is suitable for the test of a wide area measurement system (WAMS) function, the simulation test of a damping control function, the simulation test of transiently stable state analysis and control functions, the simulation test of voltage stabilization and control functions, the simulation…
