Abstract
At present, domestic thermal power units participating in deep peak load regulation need to meet the unit load response rate and the economical requirements of the low and medium loads. Although the main steam sliding pressure operation can improve the unit economy in a certain extent, the traditional single static sliding pressure curve does not consider the influence of the changing environmental parameters, heating, industrial steam and so on. This study proposes a realization method of variable load deep peak regulation technology based on condensate water. By rapidly variable load control technology of condensate water throttling and variable load deep sliding pressure optimization control system based on condensate water, according to AGC and the instruction demands of primary frequency modulation, the main steam control valve of unit and the frequency converter of condensate pump are deployed comprehensively. At the same time, according to the changes of working conditions such as environment and heating, the given main steam pressure is optimized in real-time, and the energy-saving operation of deep peak load regulation and sliding pressure are achieved. Then the economy of this technology is evaluated through comparative tests. The results show that this technology can significantly improve the overall economic efficiency of unit and meet the needs of the power grid assessment and economic operation of unit.关键词
