Distributed energy project annual main technical index calculation method

Abstract

The invention provides a distributed energy project annual main technical index calculation method, which comprises the following steps: obtaining the types of different business forms in an energy supply area of an energy station and the building area of each type, calculating the total cooling and heating load of the energy station by combining an index method, and selecting an energy station installation scheme; Determining start and stop dates of a cooling season and a heating season of the energy station according to local meteorological conditions; Determining the starting sequence priority of the equipment during refrigeration and heating; Calculating a year-round hour-by-hour cold and hot load curve of each business state; Superposing the different hour-by-hour curves, and obtaining a cold and hot time delay curve in the energy supply area of the energy station by combining the starting date of the cooling season and the starting date of the heating season; And the annual maintechnical index of the energy station is calculated by combining the energy station cold and hot time delay curve, the energy station installation condition and the equipment starting sequence priority. According to the method, the annual operation condition of each refrigeration and heating device can be calculated in detail, the proportion information of each device in cooling and heating is reflected, and the calculation result is accurate.

Description

technical field [0001] The invention relates to a method for calculating main technical indicators of a distributed energy project throughout the year, and belongs to the technical field of distributed energy utilization. Background technique [0002] The distributed energy multi-generation project is an industry encouraged by the state. Accelerating the development of distributed energy multi-generation projects can optimize and adjust the power structure, promote energy conservation and emission reduction, and promote local economic development. [0003] The distributed energy system is a second-generation energy system based on the principle of "benefit scale". The distributed energy system fueled by natural gas implements cogeneration of heat, power and cooling, which can greatly improve energy conversion efficiency and reduce energy transmission losses. With the rapid development of my country's economy and society, the rapid advancement of urbanization and the formatio...

Problems solved by technology

[0006] (1) The calculation result depends on the empirical value, and the empirical value in the manual is generally a value range, so it is easy to cause large errors;

[0007] (2) The traditional method uses the average index to calculate the total cooling and heat supply (kWh), and then uses the average energy efficiency ratio (COP) to calculate the main technical indicators of the energy station, so it cannot reflect the specific operation of each equipment in the energy station and each equipment The proportion information in the cooling and heating supply cannot provide data reference for the later operation of the energy station
