Abstract
The present invention discloses a computerized analysis system for quantified economic performance of coproducing heat and electricity and features that it has hardware system comprising SQL data base server, client terminal and printer; development platform Windows NT4.0/windows2000, MS SQL Server 7.0 and Windows2000. In the development environment of Powder Builder 6.0, quantified economic performance of coproducing heat and electricity is computerized alalyzed.
Description
The invention provides a kind of Computerized analysis system for quantified economic performance of coproducing heat and electricity, relate to the economic benefit technical field of cogeneration plant with the computer system analysis cogeneration of heat and power.
Under condition of market economy, what kind of influence heat supply brings for the economy of power plant benefit, will determine Business survival, affect the development of thermalization cause too, separate the factory and network, valency online unexpectedly, adjusting entity with factory is the current major premise of the generating plant survival and development from now on that reaches.Until the very complicated trouble of the calculating of every indexs such as profit, not seeing by retrieval has relevant Computerized analysis system report to coal consumption, station service power consumption rate, generated energy in cogeneration of heat and power in economical.
The present invention discloses a kind of Computerized analysis system for quantified economic performance of coproducing heat and electricity, has solved the Computer Analysis quantified economic performance of coproducing heat and electricity problem of utilizing.
Task of the present invention is achieved in that by sql database server, client terminal, printer and constitutes hardware configuration; Development platform is Windows NT4.0/Windows2000, MS SQL Server 7.0, Windows2000, under the development environment of Power Builder 6.0, and composition data flow process: see accompanying drawing 1.
Program module constitutes: see accompanying drawing 2.
System's major function comprises COMPUTER CALCULATION and analysis software, utilizes the investment of finance, production report numeral and the power plant construction in computing interval, and loan interest rate etc. influence whole raw data of cost, calculate the following index:
1, cogeneration plant during profit, the profit same period of tearing condensing power plant open, cogeneration of heat and power give heat
The profit value that power plant brings.
2, the cogeneration of heat and power profit break even line of cogeneration plant, existing electricity, the residing worker of caloric value
Do a little, be in what district (profit area, loss area), whether the electric heating valency is reasonable,
Much damage price differences that is full of are respectively arranged.
3, net coal consumption rate, auxiliary power consumption rate of power plant, the generated energy of the folding condensing operating mode in computing interval;
Obtain the influence amount of heat supply to power supply consumption coal, generated energy, generating plant electricity rate.
4, calculate the electricity price that breaks even in cogeneration plant's computing interval, break even the same period of folding condensing factory
Valency and both electricity price price differences that breaks even.
5, the application specific formula calculate the little index of heating power to the influence of big index.Display mode:
1, show printing the computing interval actually finishes and rolls over the condensing factory business indicator table of comparisons.
2, show to print cogeneration of heat and power and thanks to be full of balanced line and electricity, caloric value working point.
3, show printing electric heating price analysis and conclusion.
Good effect of the present invention is: utilize the scientific, rapid and accurate analysis meter of computer system to calculate every economic and technical norms of cogeneration of heat and power, and directly show printing curve curve and form, and very clear, the computer interface brevity and lucidity, the man-machine conversation operation is grasped easily; Cogeneration plant's index of the distortion that will be done by " calorimetry " is restored, and makes heat supply unit of the same type and heat supply unit, and the quantification of the every index between heat supply unit and the condensing unit relatively becomes a reality.
Embodiment
Changchun * * thermoelectric Ltd one or nine * * annual cogeneration plant is actual to finish, rolls over condensing, cogeneration of heat and power benefit calculation and analysis result: see accompanying drawing 3.
