The invention provides substation signal homologous testing methods and devices and a signal system. A substation comprises station level equipment and bay level equipment which are connected throughutilization of a network. A method comprises the steps of obtaining MMS signals formed by MMS signal points of the bay level equipment, wherein the MMS signals comprise configuration states of the MMSsignal points under effect of excitation signals; and inputting the MMS signals into the station level equipment, thereby testing whether the station level equipment works normally or not. Accordingto the methods, the devices and the signal system, consistency of test signals of the station level equipment and the test signals of the bay level equipment can be ensured, and a communication working state of the substation can be tested efficiently and accurately.
Description
technical field [0001] The invention relates to the technical field of substation signal testing, in particular to a substation signal homologous testing method, device and signal system. Background technique [0002] At present, with the vigorous development of the national power system, smart substations have been widely used. Smart substation adopts advanced, reliable, integrated and environment-friendly intelligent equipment, with the basic requirements of digitalization of whole station information, networking of communication platform, and standardization of information sharing, and automatically completes basic functions such as information collection, measurement, control, protection, measurement and detection. At the same time, it is a substation with advanced functions such as real-time automatic control of the power grid, intelligent adjustment, online analysis and decision-making, and collaborative interaction. The current smart substation usually adopts a three...
