Problems solved by technology

[0004] As we all know, the power flow program and many EMS programs are based on the steady-state model of the power system, so the data input into these programs should be steady-state values; on the contrary, if the unsteady-state data is input, there will be problems in the output

Embodiment Construction

[0046] Depend on Figure 1-8 It can be known from the illustrated embodiment that the online steady-state processing method of telemetry data includes the following steps:

[0047] (1) Establish an online steady-state processing system for telemetry data, the online processing system includes an analysis module, a preprocessing module, a steady-state processing module, and a restoration module; the analysis module is sequentially restored through the preprocessing module and the steady-state processing module module;

[0048] (2) The parsing module receives the E-format DT file of the data acquisition and monitoring control system telemetry data issued by the FTP client real-time telemetry data area of ​​the D5000 dispatching system (Q / GDW_215-2008, Power System Data Markup Language—E Language Specification ); and according to the data of the model structure (CIME file of the dispatching system), the data of active remote measurement P, reactive power measurement Q, voltage m...

Abstract

The invention relates to an online steady state processing method of telemetry data. The method includes the following steps that: an online steady state processing system of telemetry data is established; an analytical module receives the telemetry data and analyzes and screens the data; a preprocessing module performs low-pass filtering processing and re-sampling processing on the telemetry data; and a steady state processing module performs steady state processing on the telemetry data. With the online steady state processing method of the telemetry data adopted, real-time online interfacing of a steady state processing program and an automated program for electric power dispatching of a D5000 dispatching system can be realized successfully, and real-time on-line steady state processing of electric power telemetry data of a provincial power dispatching master station can be realized, bad data can be eliminated in real time, and severe fluctuation of a steelmaking load can be suppressed, and the accuracy of the telemetry data can be improved; the qualified rate of state estimation can be improved; the problem of existence of bad data in telemetry data of a data acquisition and monitoring control system which has existed for a long time can be solved; and an accurate and reliable data source can be provided for advanced application of intelligent dispatching.

Description

technical field [0001] The invention belongs to the technical field of remote measurement data processing of power system data acquisition and monitoring control systems, and relates to an online steady-state processing method of remote measurement data. Background technique [0002] In 1970, Schweppe and Larson discovered that there were bad data in the telemetry data of the power grid dispatching data acquisition and monitoring control system almost simultaneously, and proposed to use state estimation to eliminate them. The premise of eliminating bad data in state estimation is that the parameters of power grid components are accurate. Unfortunately, both theoretical calculations and measured parameters have large errors, so the bad data of telemetry has not been well resolved until now. The data acquisition and monitoring control system is the basis of power dispatching, and the telemetry data is the basic data of the power grid, which directly determines the reliability ...
