Secondary industry user loss evaluation method and apparatus under blackout state

Abstract

The invention provides a secondary industry user loss evaluation method and apparatus under a blackout state. The method comprises the following steps: obtaining power failure loss original data of typical users of a certain sector in the secondary industry at a specific time point; based on the power failure loss original data, establishing a power failure loss function model of each typical user of the sector under a unit load; based on the power failure loss function model of each typical user under the unit load and proportions of a yearly power consumption amount and a yearly total output value in the sector, establishing an economic loss function of the sector under the unit load, and obtaining a unit load economic loss value of the sector at the specific time point; establishing a power failure loss evaluation model of the sector; and solving parameters of a power failure loss evaluation model of the sector, and based on the parameters, obtaining a final power failure loss evaluation model. According to the invention, loss of users of the secondary industry under the blackout state can be accurately and effectively evaluated.

Description

technical field [0001] The present invention relates to the technical field of power systems, in particular to a method and device for assessing losses of secondary industry users in a state of major power outage. Background technique [0002] According to the "Classification of National Economic Industries" (GB / T 4754-2011), the secondary industry refers to the processing industry, which uses basic means of production for processing and sale, including mining, manufacturing, electricity, heat, gas and water production and The supply industry and the construction industry are four major parts. The representative industries introduced in "Industrial Power Consumption Analysis" include coal industry, iron and steel industry, chemical industry, petrochemical industry, aluminum industry, machinery manufacturing industry, electronic information industry, building materials industry (cement industry), textile industry , paper industry, electric power industry. Due to the high de...

AI Technical Summary

Problems solved by technology

Due to the high dependence of secondary industry users on power supply, once a major power outage occurs, not only will important production equipment be shut down or damaged, product output will be greatly reduced, and quality will be seriously reduced. If the power supply is not restored in time In severe cases, it will cause a series of serious consequences such as fire and explosion of equipment, damage to the ecological environment, and heavy casualties of personnel. The economic losses caused by power outages have important practical significance

But at present, there is no evaluation model and evaluation method that can accurately and effectively evaluate the loss of users in the secondary industry under the state of blackout
