Remote monitoring system and method of generator set analog quantity control system

Abstract

The invention discloses a remote monitoring system of a generator set analog quantity control system. The remote monitoring system comprises a data acquisition module which is used for obtaining the field data of the generator set analog quantity control system in real time, a data analysis module which is used for analyzing the field data and generating the monitoring data of the generator set analog quantity control system, wherein the field data comprises a controlled parameter, commands and feedback of an actuator, and the set value and the actual value of an automatic control subsystem. Therefore, in the embodiment, the field data is obtained through data acquisition module, the field data is analyzed in a unified way, the unified system monitoring, unified technical management and unified standard evaluation of the adjustment quality of the generator set analog quantity control system are realized, and thus the accurate monitoring of the adjustment quality is realized. The invention discloses a remote monitoring method of a generator set analog quantity control system, and the technical effect can be realized too.

Description

technical field [0001] The invention relates to the technical field of quality monitoring, and more specifically, to a remote monitoring system and method for an analog quantity control system of a generating set. Background technique [0002] Large-scale unit units in thermal power generation enterprises are typical thermal process systems. They are a huge equipment group consisting of boilers, steam turbines, generators and auxiliary equipment. The process flow is complex and there are many main and auxiliary equipment. The unit analog control system covers all the main control links of the unit, and there are many sets. Its automatic input rate is one of the main technical control indicators of various power generation enterprises and power generation groups. The adjustment quality of the analog control system reflects the automation level of the unit, which has decisive significance for the safe, efficient and environmentally friendly operation of the unit, and also dete...

Problems solved by technology

The periodic automatic disturbance test belongs to the disturbance test of working conditions. It not only has a large workload on site, but also has many problems that affect the technical management and objective evaluation of enterprises and groups during the implementation process:

[0003] Restricted by the technical level of personnel in power generation enterprises and the operating conditions of the units, the period, scope and quality of the periodic disturbance tests of various power plants are quite different; the method of automatic disturbance tests can only control the simulated quantities of the units during the test period and test conditions. Quality testing and evaluation cannot fully represent the quality characteristics of all units, units in all working conditions and in full time, and only relying on on-site thermal personnel to conduct statistics not only consumes a lot of time and energy, but also due to differences in equipment and process system configurations and personnel knowledge The deviation of the statistics results in the inconsistent number of statistical benchmark sets, and the grassroots organizations contain different subjective factors in the process of filling in the indicators.
