Embodiment Construction

[0034] The distribution network-based load parameter identification system of the present invention is mainly composed of a load monitoring master station, a data collection terminal, a data communication channel and a distribution network load parameter identification management application platform. Among them, the main function of the load monitoring master station is to receive data from fault detection and signal generators and store them regularly for use by the distribution network load parameter identification management application platform; the main function of the data acquisition terminal is to monitor the distribution network load. Active power, reactive power, voltage, and power factor angle changes on the bus. The data communication channel is mainly used for communication between the load monitoring master station and the data acquisition terminal; the main function of the distribution network load parameter identification management application platform is to p...

Abstract

The invention discloses a method and a system for distribution network load parameter identification, relates to the technology of computers and the technical field of electricity monitoring and particularly relates to the field of electricity special planning and the technical field of electricity system stabilizing analysis. The method comprises steps of preprocessing load parameters and classifying nodes; identifying load model parameter vectors in a distribution network; and processing load model parameter vectors optimally. By the aid of the method and the system, the cluster and the generalization of a main variable load model can be achieved, and the load model identification which is subjected to polymerization based on different voltage levels and outlets can be achieved. The method and the system are suitable to electricity distribution networks such as city distribution networks, oil field distribution networks and rural distribution networks.

Description

technical field [0001] The invention relates to computer technology, in particular to an intelligent power load optimization technology based on distribution network. Background technique [0002] With the rapid development of my country's national economy, the current main structure of my country's power grid has changed from a provincial independent power grid or a regional power grid with close electrical connections to a stage of regional power grid interconnection. The gradual increase in the scale of the power system makes the power system more and more complex. Everyone realizes that accelerating the automation development of the distribution network is a key link to improve the reliability of the power supply of the distribution network. Power load forecasting is an important part of distribution network planning and the basis of distribution network planning. The results of distribution network load forecasting are regional power development, grid structure adjustme...
