Method for measuring and proving saved electric energy volume in energy-saving project

Abstract

The invention relates to a method for measuring and proving saved electric energy volume in an energy-saving project. The method includes that (1) a project boundary and a project evaluation scheme are determined before the energy-saving project is implemented; (2) an energy-saving project standard period is determined, a pre-evaluation mathematic model is built, and relevant component parameters and operating data are collected; (3) the energy-saving project is pre-evaluated, and a pre-evaluation report is formed; (4) an optimal scheme is selected by referencing the pre-evaluation report, and the energy-saving project is implemented; (5) an energy-saving project statistic report period is determined, a post-evaluation mathematic model is built, and relevant component parameters and operating data are collected; (6) post-evaluation is conducted for actual saved electric energy volume, and a measuring and proving report is formed; and (7) saved electric energy volume for a long period is estimated according to the measuring and proving report, and a basis is provided for revision and implementation of an energy-saving project scheme at a later stage. The method has high operability and pertinence and has high practical value and popularization value on energy-saving projects in the field of power demand side management.

Description

technical field [0001] The invention belongs to the technical field of energy saving, and in particular relates to a measurement and verification method for saving electric power in energy saving projects. Background technique [0002] In 2010, the National Development and Reform Commission, together with six ministries and commissions, jointly issued the "Power Demand Side Management Measures", clearly proposing that the annual power saving indicators of power grid enterprises in provinces, autonomous regions, and municipalities directly under the Central Government should not be lower than those in the power sales business areas of relevant power grid enterprises in principle. 0.3% of electricity sales in the previous year. Large-scale commercial office buildings are also promoting energy-saving and environment-friendly buildings such as smart buildings and green buildings. With the advancement of energy saving and emission reduction work and the rapid promotion of contra...

Problems solved by technology

In the whole process of the energy saving project, the saving of electricity and electricity involves the comparison of the loss in the two states before and after the transformation, but the loss before and after the transformation cannot be directly measured in essence. According to the International Performance Measurement and Verification Specification (International Performance Measurement and Verification Protocol, IPMVP), through the regression analysis method, on the basis of the original energy consumption, simulate the
