Intelligent signal processing system of power grid equipment

Abstract

The invention discloses an intelligent signal processing system of power grid equipment. A data layer is provided with a database module and a real-time information receiving module, an application layer is provided with an auxiliary decision making module, an abnormal signal association analysis and diagnosis module and a fault signal analysis and diagnosis module, and a user layer is provided with a human-machine interaction module and an online decision making module. The system comprises a real-time state and a research state, both of which can realize the association analysis and diagnosis of an equipment abnormal signal before the occurrence of an accident, a fault signal diagnosis function when the accident occurs, and timely assistance to the decision of the regulation and control personnel; and meanwhile, a historical signal analysis and diagnosis result can be inquired so as to provide historical data to the case analysis and training of the regulation and control personnel. The system has expandability and can be embedded with an SCADA / EMS system; and meanwhile, the system reserves partial interfaces to facilitate the compatibility with other systems. The intelligent signal processing system of the power grid equipment ensures the universality and independence of the system function.

Description

technical field [0001] The invention belongs to the technical field of data interaction and analysis, and in particular relates to an intelligent signal processing system for power grid equipment. Background technique [0002] With the advancement of the State Grid's "three sets and five major" programs and the continuous expansion of the grid scale, the work pressure of grid regulators is increasing. For various safety and economic indicators, its information processing system lacks correlation analysis between signals such as equipment failures, abnormalities, and alarms. Faced with the massive amount of information sent to the control center, power grid control personnel rely on experience and intuition to judge the nature of grid equipment failures, which can no longer meet the needs of current grid intelligent dispatching. Research and development of intelligent energy management that integrates dispatching business and monitoring business System EMS is the key to ensu...
