Signal testing system, method and device for substation control level equipment of transformer substation

Abstract

The invention relates to the technical field of signal testing for a transformer substation, and provides a signal testing system, method and device for substation control level equipment of the transformer substation. The signal testing system for the substation control level equipment of the transformer substation comprises monitoring system equipment of the transformer substation, remote-action system equipment of the transformer substation, and the signal testing device for the substation control level equipment of the transformer substation which are connected through a substation control level network, wherein the signal testing device for the substation control level equipment of the transformer substation can obtain MMS signal points of various bay level equipment from a pre-configured substation configuration description (SCD), generate analog signals of the MMS signal points, and send the analog signals to the monitoring system equipment and the remote-action system equipment; the monitoring system equipment can determine whether the monitoring system equipment works normally or not according to the analog signals, and the remote-action system equipment can determine whether the remote-action system equipment works normally or not according to the analog signals. The signal testing system, method and device provided by the invention can solve the problems in the prior art that signal testing methods for the substation control level equipment are relatively complicated, and are relatively dependent on complete establishment of the substation control level network.

Description

technical field [0001] The invention relates to the technical field of substation signal testing, in particular to a signal testing system, method and device for substation control layer equipment. 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 structure of the current smart substa...
