Abstract
An apparatus for supplying heat and electric power and regulating electric peak is composed of the machine set for generating both electric power and heat and boiler. Its working method features that the working condition of said machine set and the heat generated by boiler are regulated according to the electric load and heat load, and a heat accumulator is used to compensate the difference between needed heat and generated heat. Its advantages include high safety and reliability.
Description
The present invention relates to the energy source and power technical field, particularly relate to operational mode that is used for the power peak regulation cogeneration of heat and power and the device that uses this pattern.
In the prior art, domestic cogeneration power plant moves in " electricity determining by heat " mode, and electric power system base lotus is born in the generating online.Present many regional power supply and demands have reached balance substantially, even the relative excess phenomenon of electric power appears, cogeneration power plant is because the needs of heat supply often generate electricity piezometric not down in the electric load low ebb phase, and push up to get at electric load peak period energy output, influenced the normal operation of electrical network.Thereby local electricity department is very strict to cogeneration power plant's generating online amount limit, makes the economic benefit of cogeneration power plant's operation to be protected, even faces the existence crisis.It is the operational mode of target that external co-generation unit is mainly taked to pursue co-generation unit self economy.Some cogeneration power plants are in conjunction with tou power price, and multiple electricity generates electricity when hanging down electricity price less when high electricity price.But because the operation of co-generation unit does not stand in whole electric power system angle, the tou power price that is adopted can't reflect that real electric load peak valley changes, thereby the power peak regulation effect can not be really played in the operation of cogeneration power plant.
At the situation of prior art and the problem of existence, purpose of the present invention provides a kind of regulating peak of electric power method and device thereof.It can make the operational mode of co-generation unit electricity by traditional " electricity determining by heat ", becomes electric peak regulating operation.Not only can alleviate the unfavorable situation that the electric load peak-valley difference constantly widens, and can obviously improve the economy of co-generation unit, for a new road has been opened up in the survival and development of following co-generation unit.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes as follows:
A kind of regulating peak of electric power method, it adopts the operating condition of adjustment cogeneration units self and the quantity of heat production of boiler to adapt to the peaking operation pattern.The steps include: that 1. situations of change according to online electric load and heating demand instruct the adjusting of cogeneration units operating mode, the electricity needs information acquisition that the variation of electric load is provided by power scheduling department.2. for extraction condensing type heat supply unit, the electric load peak period increases the steam turbine throttle flow for increasing energy output as far as possible, and increases condensing generating share; The electric load low peak period reduces the steam turbine admission as far as possible, and increases the generating share of drawing gas.For the back pressure type steam turbine unit, then only by changing the energy output that steam turbine vapour amount changes electric load peak valley phase heat supply unit.For combustion type fuel oil cogeneration units, can increase the dynamics of power peak regulation by the start and stop of cogeneration units and boiler.3. by the supply and demand difference between storage heater balance quantity of heat production and the heat load, when quantity of heat production was higher than heat load, storage heater stored unnecessary heat, when quantity of heat production is lower than heat load, and the storage heater heat release.
Realize the device of above-mentioned regulating peak of electric power method, it comprises cogeneration units and boiler, and the cogeneration units electricity is gone into electrical network.Its design feature is, the heat that described cogeneration units and boiler produce inserts the storage heater inlet, and the storage heater outlet is joined with the heat efferent duct.Be provided with break valve between storage heater inlet and the outlet.
Regulating peak of electric power method provided by the present invention under the condition that does not influence heating effect, can improve generating rate for incorporation into the power network and generating hourage, thereby has improved the economic benefit of cogeneration power plant's self-operating.Can participate in power peak regulation in addition, produce important function for the safe operation of electric power system and the raising of economic benefit.Also opened up a new road for the survival and development under the electricity market management system of following valency unexpectedly online.Equipment therefor of the present invention, equipment investment is few, and is safe and reliable to operation.Compare with prior art, the operation power pattern that " electricity determining by heat " is traditional becomes electric peak regulating operation.Reduce the electric load peak-valley difference, had huge potential economic benefit.
The invention will be further described below in conjunction with accompanying drawing and concrete execution mode.
Accompanying drawing is the device connection layout of operation method of the present invention.
Referring to accompanying drawing, realize the device of above-mentioned regulating peak of electric power, comprise cogeneration units 1 and boiler 2, cogeneration units 1 electricity is gone into electrical network.The heat that cogeneration units 1 and boiler 2 produce inserts storage heater 4 inlets.Storage heater 4 outlets are joined with the heat efferent duct, are provided with break valve 3 between storage heater 4 inlets and the outlet.
Regulating peak of electric power method of the present invention is to adopt the operating condition of adjustment cogeneration units self and the quantity of heat production of boiler to adapt to the peaking operation pattern.The steps include: 1. situations of change according to online electric load and heating demand, the heat that obtains the online energy output of unit and quantity of heat production and storage heater by operating software holds puts power, adjusting and storage heater by its software tip cogeneration units operating mode are put holding of heat, realize the electric peak regulating operation pattern.The electricity needs information acquisition that the variation of electric load is provided by power scheduling department.2. for extraction condensing type heat supply unit, the electric load peak period is full of increase steam turbine throttle flow for increasing energy output, and increases condensing generating share.The electric load low peak period reduces the steam turbine admission as far as possible, and increases the generating volume that draws gas.For the back pressure type steam turbine unit, then only by changing the energy output that steam turbine vapour amount changes electric load peak valley phase heat supply unit.For combustion gas or fuel oil cogeneration units, can increase the dynamics of power peak regulation by the start and stop of cogeneration units and boiler.3. the heat of cogeneration units 1 and boiler 2 outputs is imported storage heater 4, by the supply and demand difference between storage heater 4 balance quantities of heat production and the heat load.When quantity of heat production was higher than heat load, storage heater 4 stored unnecessary heat, storage heater 4 heat releases when quantity of heat production is lower than heat load.The effect of break valve 3 is maintenances or uses when breaking away from storage heater 4.
