System.
Background technology
As the fast development of China's economy and living standards of the people increasingly improve, domestic installed capacity in power grid expands therewith
Greatly.However, since power structure changes in recent years in China, i.e., primary industry electricity consumption declines, second, third industry electricity consumption
Amount rises, and power grid peak-valley difference is caused gradually to increase；At the same time, the new energy such as wind energy, the solar energy greatly developed in recent years are sent out
Power technology, in order to coordinate the online of renewable energy power generation, needs not participate in tune originally the problem of disconnection there is energy supply and demand
The Power Plant at peak will also undertake certain peak regulation task, these undoubtedly all can cause peak load regulation network amplitude and difficulty increasingly
Greatly.
Further, since the most of power plants in China are the thermal power plants based on fire coal, and the proportion very little of hydroelectric power plant, northeast ground
This feature in area is especially prominent, and is carried out in a deep going way with China's energy-saving and emission-reduction work, many coal-fired electricity of the Northeast
Factory is all transformed into the cogeneration power plant for capableing of heat supply in winter, this behave improves the utilization ratio of the energy to a certain extent
And the benefit of power plant, but there is also some technical deficiencies.Currently, the power plant of cogeneration of heat and power mostly uses electricity determining by heat

Pass through heat exchangers for district heating heat supply, regenerative apparatus accumulation of heat when big；When quantity of heat production is few, regenerative apparatus heat release substitutes heat exchangers for district heating
Heat supply network return water is heated in part steam extraction, and thermal substation is sent to after being mixed with heat exchangers for district heating water outlet.The patent is carrying to a certain extent
The high peak modulation capacity of cogeneration units, but thermal energy is subjected to gradient using not high so as to cause heat utilization rate；
In addition there is no in view of when unit quantity of heat production is reduced, the heat that extracted steam from turbine heat is released with regenerative apparatus is still for the patent
This case that cannot meet heat user demand, this cannot be guaranteed that Heating quality is always when unit participates in the variation of peak load regulation network quantity of heat production
It is constant.
