Problems solved by technology

[0003] Since the measuring instruments of the power plant often work in harsh environments such as high temperature, vibration, and corrosion, they are prone to failure, resulting in wrong data collected by the data acquisition system; in addition, the measurement data may also be affected by interference, drift, and measurement environments. errors, which are often difficult to detect intuitively
In addition, various errors in the measurement data often destroy the balance relationship in the mathematical model

Abstract

The invention relates to a power station condition online diagnosis and operation optimization system based on data coordination. The power station condition online diagnosis and operation optimization system comprises an AF platform, a data coordination technology and a mass data processing technology, wherein mechanism mathematical models of components form a unit system model based on the mechanism mathematical models; due to the combination of the data reconciliation technology and a power station system model, more accurate and reliable data input is provided for the unit system model; mass real-time operating data of a unit are guaranteed. By adopting an advanced computer technology, the system is combined with power station generation process and system characteristics, utilizes an existing real-time database system of a power station, builds and completes a complete set of power station condition online diagnosis and operation optimization system based on data coordination; in virtue of AF products, a visual editing and operating environment with data coordination, equipment characteristic analysis, performance computation and fault diagnosis is realized; performance monitoring and state diagnosis information publishing functions based on business application are completed.

Description

(1) Technical field [0001] The invention belongs to the field of power system data processing, and in particular relates to a power station state online diagnosis and operation optimization system based on data coordination. (2) Background technology [0002] Power plant performance monitoring is a process of continuous, regular and regular repetitive calculation and evaluation of the power plant and its power generation equipment production capacity and efficiency using real-time measurement data of the power plant. The purpose of performance monitoring is to continuously assess the performance degradation of the power plant and its equipment, and provide data support for the power plant operators to locate faults, improve performance, and economic decisions related to scheduling, maintenance, and operation optimization. Periodic, real-time performance calculation is the main task of power plant monitoring. The specific content of the calculation depends on the available real-ti...
