In 2019, State Grid Gansu Liujiaxia Hydropower Plant achieved 650 million kilowatt hours of water-saving power generation, which is equivalent to saving 227500 tons of coal, 596000 tons of carbon dioxide and 1933 tons of sulfur dioxide. The effect of energy conservation and environmental protection is significant.
It is reported that in 2019, Liujiaxia hydropower plant will make full use of the favorable situation of the water coming from the upper reaches of the Yellow River, actively carry out the potential tapping and efficiency increasing, and effectively improve the economic operation level. Since the summer of 2019, there has been more precipitation in the upper reaches of the Yellow River. Influenced by the spring snowmelt in the upper reaches of the Yellow River and the earlier water inflow, the water inflow in the upper reaches of the Yellow River has increased sharply since April. In June, the cumulative rainfall in the Yellow River Basin is 37.5mm, 10% more than the same period of the whole year, during which, the upper reaches of the Yellow River is 28% more than the same period of the whole year. The number of two floods in the upper reaches of the Yellow River occurred nearly 20 days earlier than last year.
In the face of the severe flood control situation, the cadres and staff of Liujiaxia Hydropower Plant unite as one, strictly implement the dispatching instructions, timely open the gate for flood discharge, and further strengthen the special inspection of equipment and equipment. In the case of cumulative flood discharge of 2.925 billion cubic meters, all generating units, water release structures and gate opening and closing equipment have experienced long-term and heavy load operation detection.
In order to ensure the safety of the Yellow River during the flood season, in order to achieve more power generation, Liujiaxia hydropower plant has made great efforts to "save water", strengthen the contact with the dispatching, adjust and report frequently, and reduce the idling time of the unit through timely start-up and shutdown. According to the change of reservoir water level, the loa
