Method and system for displaying fired coal quality in real time

Abstract

The invention discloses a method for displaying fired coal quality in real time. The method comprises the following steps: searching for demanded measured point data from an SIS (Safety Instrumented System) system by a measured point base via a thermal power plant system and storing searched demanded measured point data; analyzing demands by an index base according to working conditions, acquiring one or more measured point data from the measured point base, calculating index data according to an index formula and measured data acquired from the measured point base, and transmitting the generated index data to a typical working condition index database; in real time processing and updating coal storage information of each coal bunker by a real-time coal storage information management device according to the index data, wherein the coal storage information involves in beginning and terminating time of coal bed formation; acquiring the corresponding coal quality information of the coal bed including real-time fired coal by matching the beginning and terminating time with the manually inputted coal supply information, thereby obtaining the real-time fired coal heat value of the coal bunker. According to the displaying method, coal quality conditions at present and after some time can be absolutely clear.

Description

technical field [0001] The invention belongs to the field of coal mine management, and in particular relates to a method and a system for real-time display of the coal quality of furnace coal. Background technique [0002] At present, the SIS system of thermal power generation companies has become more popular in recent years, but there are various problems in the current SIS system, 1) the coal quality of the coal entering the furnace cannot be displayed in real time, 2) although there is real-time sampling and testing of the coal entering the furnace, But the cost is high, and there are radioactive elements, and the measurement is inaccurate when the coal quality changes greatly; 3) At present, the test results of the coal entering the furnace lag behind, and the general results are not available until the next day, which has little guiding significance for operation adjustment; 4 ), the current test results of coal quality into the furnace are the overall results of t...
