Abstract: With the implementation of national policies, new energy in China′s power grid occupies more and more proportion, accordingly, 1000 MW thermal power generating units will gradually shoulder the responsibility of regulating the load peaks and valleys in the power grid, we will face more frequent and more persistent 30% of the depth of the peak requirements, combined with the actual conditions of 30% of the depth of the peak of a power plant, the peak of the process of the feed pump performance research and analysis, combined with the actual situation of the unit to put forward countermeasures. Performance research and analysis, combined with the actual situation of the unit to put forward countermeasures.
