Embodiment Construction

[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] The total power loss ΔP of the power supply and distribution system line L Including conduction loss to ground P G and line load loss P R Two parts, since the line-to-ground conductance loss is mainly caused by insulator leakage and corona, when the user's power supply voltage is 110kV and below, it can be ignored; line loss generally refers to line load loss, which is related to current carrying capacity, operating voltage, It is related to line type, transmission distance and load distribution along the line. The mathematical expression is:

[0032] Δ P L = 3 I 2 R = P 2 R U ...

Abstract

The invention relates to a method for measuring and verifying the energy saving of power supply and distribution lines, including: 1) determining the project boundary; 2) determining the base period and the length of the statistical report period; 4) preparing tables; 5) collecting data and Fill in the form; 6) Determine the energy efficiency parameters; 7) According to step 6), evaluate the energy saving of power supply and distribution lines and give a report. The invention can effectively monitor the energy saving and ensure the economic benefits of energy saving in project transformation. The present invention does not need to measure and collect the energy efficiency data of the base period before the transformation of the line, and does not need to establish a model of the transformed line through the method of "calibration simulation" to obtain the reference value of the energy consumption after calibration. It only needs to collect the electrical parameters of the transformed line. Calculate the energy saving of the line, simplify the process of measurement and verification, and reduce the manpower and financial input of measurement and verification.

Description

technical field [0001] The invention relates to the technical field of power system energy saving, in particular to a method for measuring and verifying energy saving of power supply and distribution lines. Background technique [0002] Measurement and verification of energy savings is the final step in an energy-saving retrofit project. With the widespread promotion of grid energy conservation, energy efficiency measurement and verification has become a method for grid companies to accurately and efficiently evaluate their energy-saving and loss-reduction solutions. Measurement and verification is an important technical assurance link in power grid energy-saving transformation. Regular measurement and verification can effectively monitor the energy-saving energy, and can adjust the energy-saving transformation plan in time through data changes to ensure energy-saving benefits. [0003] At present, there is a lack of unified standards for the procedures and methods of energ...
