Embodiment Construction

[0033] Such as figure 1 Shown is the flowchart of the embodiment of the present invention, and the specific steps are:

[0034] 1) Extract PMS system data to establish a grid model; the extracted data includes grid structure data and grid equipment parameters;

[0035] Since the data extracted from the PMS system is theoretical data, the established grid model is a theoretical model, that is, the theoretical model only includes all components and grid structures in the grid.

[0036] 2) Real-time collection of the status of tie switches and section switches in the SCADA dispatching system and distribution automation system, and establish a real-time operation mode model of the distribution network through state identification;

[0037] Since the power grid model in step 1) is a theoretical model, it is necessary to obtain the data of the SCADA dispatching system, so as to know the on-off status of each switch in the power grid model, so as to obtain the real-time operation mo...

Abstract

The invention discloses a real time identifying method for line loss transaction of a power distribution network, comprising: building a power network model through extracting PMS system data, collecting the states of a interconnection switch and a section switch in real time, identifying the operation mode of the power distribution network, obtaining the operation data of a circuit gate and a distribution transform gate in real time, calculating statistic line loss, calculating theoretical line loss combining network parameters and gate data, comparing the difference value of the statistic line loss and the theoretical line loss, positioning an abnormal region, identifying the line loss transaction, realizing abnormal region identification, abnormal factor analysis and targeted treatment. Through obtaining the operation information and data of the power network in real time, calculating the statistic line and theoretical line loss and positioning the abnormal region according to the difference value, the invention overcomes the defects at the present stage that information is incomplete and not visual in analyzing the line loss transaction, no theoretical value is taken as the reference in analyzing the line loss transaction, and the obtained analyzing result lags behind seriously.

Description

technical field [0001] The invention belongs to the field of power system operation and monitoring, and in particular relates to a real-time identification method for line loss abnormalities of distribution networks. Background technique [0002] Power grid power loss (referred to as line loss) is an important comprehensive technical and economic index for electric power enterprises, and also reflects the planning and design, production technology and operation management level of the power grid. The power loss generated by the power grid during the transmission of electric energy directly affects the efficiency and economic benefits of electric power. With the deepening of power system reform, whether the operation of the power grid is economical, whether the technical means of power supply and consumption management are scientific, etc., all involve the operating costs of power grid enterprises and the overall economic benefits of the whole society. Therefore, reducing li...
