Multimode data acquisitions and processing method applied to power automation system

Abstract

The invention discloses a multimode data acquisition comprising steady data (energy management system acquisition), dynamic data (wide area measurement system acquisition), transient data (fault signal system acquisition) applied to power automation system and a processing method. In the method, multimode data are uniformly indexed by measuring multimode, and multimode data acquisition and processing are realized by using real-time database collection memory technology and combining access method of equation and C / S mode so that the efficient memory and index of multimode data of power system in integrated system are realized and the high-efficient reliability of network and data transmission is also guaranteed, thereby realizing the unique interface for accessing and managing multimode data for the subject, providing basic-level support for further data analysis processing, and creating conditions for intellectualized dispatching system.

Description

technical field [0001] The invention belongs to the technical field of protection and control in electric power automation systems, and in particular relates to a method for collecting and processing integrated multi-state data. Background technique [0002] The energy management system (EMS) of the power grid dispatching center at all levels collects the operating status and measurement values ​​of the equipment in the power grid through the remote terminal unit (RTU) installed in the power station, so that the dispatching and operating personnel can track and adjust the operating status of the power system in time. What EMS collects is steady-state, low-sampling-density power grid time-section data. [0003] The phase angle measurement unit (PMU) and the wide area measurement system (WAMS) based on it that have emerged in recent years are a powerful supplement to EMS. PMU can provide power system measurement data with higher sampling density, making it possible to It is p...

Problems solved by technology

[0005] Steady state, dynamic, transient and other multi-state data focus on the operation information of the same power system object and complement each other. However, due to different emphases and technical limitations, most dispatch centers need to establish different power automation systems to These information are processed separately, which causes a waste of hardware resources, channel resources, human resources, etc., and limits the comprehensive processing and analysis of these types of data, which is not conducive to the realization of intelligent dispatching of the power grid.
