摘要:

为解决我国冬季电网调峰以及新能源消纳问题,低压缸零出力技术被提出,并且成为一种重要的热电联产技术。在研究了大量文献资料的基础上,简要介绍了低压缸零出力技术的应用场景和技术原理,并分别对低压缸零出力技术的理论研究、在实际工程中的应用进行了论述和评价。低压缸零出力技术作为一种电厂运行方案,具有调峰能力显著、改造成本低、经济性高的特点,虽然该方案具有十分广阔的发展前景,但要推广其应用,仍有很多实际问题亟须解决。

Abstract:

In order to solve the problem of peak load regulation in winter and new energy consumption in China, zero-output technology of low-pressure cylinder was proposed. On the basis of studying a large number of literature materials, this paper briefly introduced the application scenario and technical principle of low-pressure cylinder zero-output technology, and discussed the theoretical research and application of low-pressure cylinder zero-output technology in practical engineering. As a kind of power plant operation scheme, low-pressure cylinder zero-output technology has the characteristics of significant peak regulation capability, low reconstruction cost and high economy. Although this scheme has a very broad development prospect, there are still many practical problems to be solved urgently if we want to promote its application.

Key words: steam turbine, low-pressure cylinder, zero-output technology, power grid peak load regulation, combined heat and power generation
