Problems solved by technology
[0013] This set of system has a complete structure and can meet the requirements of the national unified dispatch. However, how to identify the accuracy of the data collection of the online monitoring device of the coal consumption online monitoring system during the implementation process, because some unpredictable factors will cause the data collected on site to occur. This kind of problem has no solution in this system. At the same time, it is found that the direct input of abnormal data will have a great impact on the calculation results of power supply coal consumption, making this system unable to achieve fairness, principles of fair operation

Embodiment Construction
[0026] Embodiments of the present invention, such as figure 1 As shown, the present invention is connected with the on-site data acquisition input signal line of the coal consumption online monitoring system, and it includes the following functional modules:
[0027] The reference module is connected with the abnormal data determination module, and acts as a reference for comparison with the data collected on site by the coal consumption monitoring system; The rated operating state plus and lower deviation value, the upper and lower deviation value is 2% of the rated operating state of the generator set.
[0028] The abnormal data determination module is connected with the abnormal data replacement module, and its function is to determine whether the data collected on site by the coal consumption monitoring system exceeds the reference range of the reference module. The data replacement module emits a signal;
[0029] The abnormal data replacement module is connected with th...

The invention discloses a system for determining and replacing abnormal data in a coal consumption online monitoring system, which comprises a reference module, an abnormal data determining module, an abnormal data replacing module, and an alarming and recording module. When the data input by the system exceeds the optimal operation range of the system, the abnormal data replacing module replaces the abnormal data to ensure that the data input into the coal consumption online monitoring system cannot generate large deviations, so a fair and judicial operation principle among a plurality of the systems is ensured as much as possible, the national policies of saving energy, reducing emission and optimizing scheduling are carried out better, and further complementation and perfection are made for the execution of an electric power generation energy consumption online monitoring system of a power network energy-saving scheduling thermal power generating unit.
Description
technical field [0001] The invention relates to a system for judging and replacing abnormal data in an online coal consumption monitoring system, belonging to the technical field of thermal power generation. Background technique [0002] In order to better implement the national energy saving and emission reduction optimization scheduling policy [Guobanfa [2007] No. 53], it is necessary to comprehensively consider power generation energy consumption and pollutant emission levels in power grid scheduling, that is, it is necessary to determine that within the next 24 hours Which generating units in the power plant should be operated to achieve the best energy-saving and emission-reduction optimization effect. [0003] Guizhou Power Grid Corporation took the lead in China in organizing the research and development of a set of online monitoring system for power grid energy-saving dispatching thermal power generation energy consumption in accordance with relevant national technic...
