Embodiment Construction

[0041] The present invention will be further described below in conjunction with specific examples.

[0042] The following table shows the hourly data list of a 135MW coal-fired generating unit in Jiangyin area. The desulfurization process is wet desulfurization, and the no-load current of the slurry circulation pump is 20A; the denitrification process is SCR, and the dust removal method is bag filter + wet electrostatic precipitator (two The rated value of the secondary voltage is 72kV, and the rated value of the secondary current is 1200mA), the specific parameters are as follows:

[0043]

[0044]

[0045] (1) Pollutant emission concentration

[0046] Sulfur dioxide concentration: 23.15*21 / (1.4*(21-5.5))=22.4mg / m 3

[0047] Nitrogen oxide concentration: 38.11*21 / (1.4*(21-5.5))=36.9mg / m 3

[0048] Smoke concentration:

[0049] 1.26*21 / (1.4*(21-5.5))*(273+79.8) / 273*101325 / (101325+292.03) / (1-11.22%)=1.76mg / m 3

Abstract

The invention discloses a coal-fired power generating set ultralow emission environmental protection electricity price monitoring method. Pollutant emission concentration is calculated according to coal-fired power generating boiler pollutant emission data and key auxiliary parameter data of desulphurization, denitration and dedusting systems so that real-time supervision and assessment of the operation situation of coal-fired boiler environmental protection facilities are realized, and finally ultralow emission environmental protection electricity price assessment cost is calculated. Therefore, environmental protection electricity price real-time and online assessment of different capacity levels of machine sets and different desulphurization, denitration and dedusting technologies is realized, and the technical means for real-time supervision and dynamic assessment of standardization of coal-fired power generating set ultralow emission is provided for the related government departments.

Description

technical field [0001] The invention relates to an ultra-low-emission environment-friendly electricity price monitoring method for a coal-fired generating set, which realizes unified management of efficient and reliable operation of desulfurization, denitrification, and dust removal facilities of the coal-fired generating set, and belongs to the technical field of automatic control of electric power systems. Background technique [0002] In September 2014, the National Development and Reform Commission, the Ministry of Environmental Protection and the National Energy Administration jointly issued a notice on the "Coal Power Energy Conservation and Emission Reduction Upgrading and Transformation Action Plan (2014-2020)", which requires: (1) Active units: By 2020, the emission concentration of air pollutants in the eastern region will basically reach the level of gas turbine units after transformation for public coal-fired generating units of 300,000 kilowatts and above, self-c...
