Problems solved by technology

[0004] The simple optical axis rotor operation mode, due to its large steam extraction, is constrained by the small heating load in the early and late stages of heating, so that the unit in the optical axis rotor operation mode cannot be put into operation in the early and late stages of heating.
At present, no heating unit in China is equipped with a peak-shaving energy storage system. The heat storage and release device used in the cogeneration unit already in operation abroad is mainly to solve the problem of inconsistent heat supply demand and heat supply, and to realize The peak-shaving and valley-filling function of heating, but the deep peak-shaving function of the unit is not considered

Abstract

The invention relates to a peak regulation energy storage system for a condensed steam type turbine unit and an operation adjusting method of the peak regulation energy storage system. By means of the optical axis rotor technology, steam is extracted to be used for supplying heat, so that electrical loads of the unit are reduced; and then a heat storing and releasing system is arranged, the functions of peak clipping and valley filling of the system are utilized, and on the premise of meeting heat loads in the heating season, the electrical loads of the unit are reduced to the minimum. The electricity and heat contradiction within the heating period in the northern area can be relieved, flexibility and elasticity of power grid dispatching are improved, and the system is suitable for being vigorously popularized.

Description

technical field [0001] The invention relates to the technical field of heat supply, in particular to a peak regulation energy storage system and an operation regulation method of a condensing steam turbine unit. Background technique [0002] At present, the domestic demand for electricity is growing slowly, and the contradiction of excess electricity is becoming more and more prominent. On the other hand, the heating market is growing day by day, and more and more pure condensing units are being transformed into heating units. With the rapid development of clean energy wind power technology, hydropower technology, and photovoltaic technology, clean energy power generation technology should be given priority in the power dispatching process. However, in some areas, due to the inability of the power grid to fully consume, the problems of abandoning wind, water and light are becoming more and more serious, which has become the main contradiction affecting the healthy developmen...
