Measuring and verifying method for electric power and electric quantity conservation of electric power boost reconstruction

Abstract

The invention provides a measuring and verifying method for electric power and electric quantity conservation of electric power boost reconstruction. According to the method, the electric power and electric quantity conservation of a project is calculated by measuring the parameters obtained before and after the boost reconstruction in the project boundary, and thereby reliable basis is provided for gaining the benefit on energy conservation. The method comprises the following steps: 1) defining the project boundary before the electric power boost reconstruction; 2) determining a project statistics reporting period; 3) determining static parameters of elements in the project boundary before and after the boost reconstruction, and acquiring dynamic running parameters within the project boundary through test equipment after the boost reconstruction; and 4) establishing a mathematical model for the electric power and electric quantity conservation, and calculating the conserved electric power and the electric quantity of the project. By adopting the measuring and verifying method provided by the invention, the actual operation steps are simplified, the input of the labor and the cost is reduced, and the final calculating results of the electric power and electric quantity conservation is more scientific and reasonable; and the measuring method and verifying method is higher in operability and pertinence, and has higher application value in the field of energy conservation and loss reduction of power systems.

Description

Problems solved by technology

[0004] In the whole process of the power step-up transformation project, the measurement and verification of power saving and electricity consumption is the last step of the energy-saving transformation project. For measurement, the International Energy Efficiency Measurement and Verification Specification (IPMVP) points out that the difference between the simulated energy consumption value of the original equipment (unmodified) under the current load condition and the measured energy consumption value during the reporting period makes the measurement and verification process Complex and cumbersome, and the specification does not point out the specific implementation method

It can be seen that the specification has only important guiding significance, but lacks operability
