Unit load optimum distribution method of oxygen manufactory

Abstract

The invention discloses a unit load optimum distribution method of an oxygen manufactory; the method comprises the following steps that the maximum loads, the minimum loads, the highest load rising speed and the highest load dropping speed of all oxygen generation units are acquired; statistical analysis is conducted on the cost data, amount of oxygen and ambient temperature of the oxygen manufactory, a cost characteristic curve at different ambient temperatures is worked out; the statistical analysis is conducted on working conditions in summer and in winter; the statistical load precision is configured to be 1 percent of a measuring range; the mean value of power consumption in each measuring range is adopted; the stability and the safety indicators of the units are calculated according to the real-time data of the units, and whether the units participate in the load optimum distribution or not is worked out by integrating marks for participating in the load optimum distribution which are manually set; and the characteristic parameters, cost characteristic curves, ambient temperature and signals for participating in the load optimum distribution of the units are read, load optimum distribution is carried out, and on-line optimum distribution results and offline optimum distribution results are output. The optimum distribution method has the characteristics of safety, economy and quickness.

Description

technical field [0001] The invention relates to a method for optimizing the load distribution of each unit in an oxygen plant, which is used for optimizing the load distribution of each oxygen generating unit. Background technique [0002] Modern iron and steel plants generally use multiple oxygen generators to complete the production of oxygen, nitrogen and argon. The capacity, load response speed, and cost corresponding to each output of each oxygen generator are different. The performance will be different after a period of maintenance; moreover, the oxygen generating unit is a large power consumer in the steel plant. Taking Baosteel Branch as an example, it takes up about 17% of the electric energy. Plant-level unit load distribution is to determine the load of each unit to optimize the economy. [0003] The ratio of foreign oxygen generator capacity to million tons of steel is generally 1 to 1.1. According to the survey results, the current domestic ratio is more suita...
