[0002] The power plan is managed and controlled by the State Grid, and the power plan allocated to power generation companies is the economic lifeline of each power generation company. However, at present, when power generation companies declare power plans, they only do qualitative analysis and do not conduct quantitative analysis.
In addition, heat supply and power supply can be said to be two relatively independent markets, and few power generation companies conduct real-time analysis and control management of heat and electricity asymmetry

The invention discloses a control method for cogeneration power generation quantity of a cogeneration unit. The control method comprises the steps of firstly, building a thermoelectric data receiving and monitoring channel synchronous with a provincial dispatching planning system, wherein the step of building the thermoelectric data receiving and monitoring channel comprises the steps of arranging a thermoelectric data receiving server and arranging a thermoelectric data monitoring server, the thermoelectric data receiving server is sequentially connected with a mirror image PI system, a forward isolation device and an SIS system, the SIS system is connected with a DCS system, the DCS system is connected with the provincial dispatching planning system, and the thermoelectric data monitoring server is connected with the thermoelectric data receiving server; secondly, calculating minimum power generation quantity required by power generation equipment by calculation of fixing heat based on power; thirdly, calculating market demand difference electric quantity according to a market heat supply plan and actual heat supply quantity; and finally, performing electric quantity demand statistics to control the power generation quantity of the cogeneration unit. Compared with the prior art, analysis of fixing heat based on power and fixing power based on heat is performed on the cogeneration unit in real time, the technical bottleneck is broken through, real-time and asymmetric analysis, management and control of a thermoelectric market are achieved, and real-time control and management on the power generation quantity of the cogeneration unit are achieved.
Description
technical field [0001] The invention relates to the control and management of power generation in daily production by power generation enterprises, in particular to a method for controlling the power generation of cogeneration of heat and power units. Background technique [0002] The power plan is managed and controlled by the State Grid, and the power plan allocated to power generation companies is the economic lifeline of each power generation company. However, at present, when power generation companies declare power plans, they only do qualitative analysis and do not conduct quantitative analysis. In addition, heat supply and power supply can be said to be two relatively independent markets, and few power generation companies conduct real-time analysis, control and management of heat and electricity asymmetry. [0003] With the continuous in-depth reform of the electricity market, higher requirements are put forward for the lean management of enterprises. Under the app...
