Abstract

A method for energy saving and loss reduction of distribution stations based on load forecasting and phase sequence optimization, including: collecting data of distribution stations; using EM algorithm to fill in missing data values; The outlet three-phase current is used as the daily load curve of each phase, and the line power flow is calculated using the forward push-back method to obtain the theoretical line loss of the distribution station area; based on historical data, the outlet three-phase current and The daily electricity consumption of each user in the distribution station area; the optimal commutation mathematical model with the goal of the lowest line loss in the distribution station area and the least number of commutations during the commutation process is established, and the genetic algorithm is used to solve the problem, and the phase modulation of each user is obtained. Sequence; compare the user's line loss and three-phase unbalance before and after adjusting the phase sequence. The invention can effectively predict the operation data of the distribution station area, and is applied to the phase sequence adjustment of the distribution station area, so that the station area can realize energy saving and loss reduction.

Description

Technical field [0001] The present invention relates to the field of power grid energy saving and loss reduction technology, specifically to a distribution station area energy saving and loss reduction method based on load prediction and phase sequence optimization. Background [0002] Energy saving and loss reduction have far-reaching significance for the economic operation of the power system, but in the low-voltage distribution network of the three-phase four-wire system, most of the loads are single-phase access, and the difference in the operating time and uneven distribution of the load of single-phase access will lead to the emergence of three-phase load imbalance, which will lead to the occurrence of neutral line current caused by line loss and distribution and transformation energy loss aggravation, resulting in high loss of distribution network. The structure of China's low-voltage distribution network is complex, and the nature of the load is becoming more and more di...
