Abstract

The invention discloses a flexibility-oriented deep peak regulation transformation scheme for a straight condensing unit. The flexibility-oriented deep peak regulation transformation scheme for the straight condensing unit comprises the steps of S1, designing a transformation scheme from four aspects of a stable combustion technology, coal pulverizing system optimization, a wide-load denitration technology and a control optimization technology by analyzing characteristics and a transformation target of the straight condensing unit; S2, applying an oxygen-enriched clean stable combustion technology to realize low-load operation stable combustion and low NOx emission; S3, applying an improved dynamic separator to a coal pulverizing system to improve the combustion quality; S4, putting a zero high-pressure heater into the low-load operation state to increase the smoke temperature of an inlet of a denitration system and then to realize low-load denitration; and S5, dynamically adjusting the change rate of a sliding pressure given value through an intelligent sliding pressure control technology to optimize control. According to the flexibility-oriented deep peak regulation transformation scheme for the straight condensing unit, a good reference is provided for flexible transformation.

Description

technical field

[0001] The invention relates to the field of flexibility transformation of pure condensing units, and more specifically, relates to a flexibility-oriented deep peak-shaving transformation scheme of pure condensing units. Background technique

[0002] With the vigorous promotion of clean energy structure reform, my country's new energy power generation has grown rapidly. According to the statistics of the National Energy Administration, the installed capacity of wind power and photovoltaic power generation in my country has increased by an average of 34% annually in the past ten years, and the average annual increase in power generation has been 32%. It is estimated that in 2025 and 2035, my country's new energy installed capacity will reach 700 million and 1.4 billion kilowatts respectively. However, new energy power generation has the characteristics of randomness, volatility, and intermittency, and its proportion continues to increase rapidly, which poses ...
