600MW unit circulating water energy-saving optimization operation prompting method

Abstract

The invention discloses a 600MW unit circulating water energy-saving optimization operation prompting method. According to the method, through designing a data acquisition model, data acquisition is carried out on circulating water temperature, unit load and condenser vacuum degree, a data sample library is established, and collected data are uploaded to the data sample library; the contents in the data sample library are screened, sorted and stored, and the running state of the unit is monitored in real time; circulating water optimization operation technical measures are judged through the prompt logic, the circulating water optimization operation mode is given in combination with the operation working condition, the state and the performance of a circulating water pump are monitored, operation personnel can be prompted to adjust in time, and the problems that the energy consumption of the unit is increased as existing circulating pump operation optimization measures are not timely executed and the energy waste is caused as circulating switching is not timely are solved.

Description

technical field [0001] The invention relates to the field of electric power production, in particular to a prompt method for energy-saving optimized operation of circulating water of a 600MW unit. Background technique [0002] In the actual production process of the power plant, the power consumption of circulating water is the second largest auxiliary machine besides the induced draft fan. Most power plants have introduced technical measures to optimize the operation of circulating water, and judge whether to switch between high-speed and low-speed circulating pumps or booster pumps by human judgment. The operation of the start-up pump cannot be changed in time according to the load, circulating water temperature, and the vacuum degree of the condenser to reach the latest working condition. If the adjustment is not timely, certain resources will be wasted. The existing circulating water optimization operation technology has the following problems: [0003] 1. Through human ...

Problems solved by technology

[0002] In the actual production process of the power plant, the power consumption of circulating water is the second largest auxiliary machine besides the induced draft fan. Most power plants have introduced technical measures to optimize the operation of circulating water. The operation of the start-up pump cannot be changed in time according to the load, circulating water temperature, and the vacuum degree of the condenser to reach the nearest working condition. If the adjustment is not timely, certain resources will be wasted. The existing circulating water optimization operation technology has the following problems:

[0003] 1. Through human judgment, the business level and response time are not timely;

[0004] 2. Once the circulating water volume is insufficient, the vacuum degree of the condenser drops and the circulating pump is not started in time or switched to a high-speed pump operation, which reduces the operating economy of the unit, and there are certain safety hazards if it is too low;

[0005] 3. When the vacuum degree of the condenser is greater than the optimal vacuum, the circulating water pump is not shut down in time or switched to low-speed pump operation, resulting in unnecessary waste of energy
