Embodiment Construction

[0118]Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in further detail:

[0119] A method for measuring and verifying power saving during boost operation of distribution lines, the method comprising:

[0120] (1) Determine project boundaries, agreed parameters and measured parameters;

[0121] (1.1) Determine the project boundary

[0122] The determination of the project boundary includes the following situations:

[0123] Situation 1: The line between the beginning of one outgoing line of the transformer bus bar and the T node of the branch line of the main line is transformed by step-up;

[0124] Case 2: If the beginning of the line is a T-node on the main line, the project boundary is the line between the starting end and the next T-node or terminal node on the main line (when the T-node at the beginning is the last one on the main line);

[0125] Case 3: If the line is a branch line and the beginning of the line...

Abstract

The invention provides a method for measuring and verifying saved electric power and electric quantity in boosting operation of a power distribution line. The method includes the following steps that: (1) project boundaries, agreed parameters and measured parameters are determined; (2) the loss of electric quantity is calculated; (3) an adjustment value Am is calculated; and (4) a calculation model of saved electric power and electric quantity is established, and the saved electric power and electric quantity are calculated. The method of the invention has high operability. According to the method, source data used in calculation are acquired with a high frequency order, and therefore, theoretically, the numerical value of the source data can reproduce actual conditions more authentically; the optimally-designed calculation model is used in combination, and therefore, the accuracy of measurement and verification can be effectively improved; the calculation model of saved electric quantity has significant time sequence performance and iterativeness, and therefore, a computer can be utilized to process a large quantity of acquisition data conveniently, and data introduction, data processing and the calculation of the saved electric power and electric quantity in measurement and verification processes can be completed automatically, the input of manpower and material resources in verification work can be greatly decreased, and work time can be shortened.

Description

technical field [0001] The invention relates to a verification method for energy saving, in particular to a measurement and verification method for power saving during boost operation of distribution lines. Background technique [0002] According to the IEC standard, if the 20kV voltage is selected to ban the 10kV (6kV) voltage commonly used in my country, that is, the voltage is reduced from 110kV to 20kV, and then reduced to 0.4kV for power supply, which can significantly improve the power supply capacity of the line and reduce the transmission loss of the line. For power supply areas with high load density and rapid growth in power demand, such as industrial parks, development zones, and new urban areas, where the contradiction between rapid economic development and limited land resources is prominent, 20kV power supply and distribution can effectively reduce the distribution density of substations and lines, and save power grid construction. invest. [0003] When the re...
