In April, the hydropower generation in the upper Yellow River hit a record high

In April, the cascade hydropower stations and photovoltaic power stations in the upper reaches of the Yellow River maintained a strong momentum of power generation. The cumulative power generation was 3.8 billion kWh, a 35.7% increase over the same period of history, creating a new high for power generation since the establishment of the Yellow River. At the same time as the hydropower station and various photovoltaic power stations are generating electricity, the major economic and technical indicators of each power station also maintain the advanced level of similar domestic units.

In order to ensure the power generation, the company's power sector focused on "safety and multi-power generation" work, combined with different seasons of safe power generation requirements and practical problems, developed the main measures and methods to ensure safe production, complete power generation tasks and enhance economic efficiency. Strictly enforced. The Company also carried out standards for safe production standardization, construction of safety and health ring systems, and troubleshooting and treatment of hidden troubles, strengthened efforts for equipment rectification work, achieved breakthroughs in power plant cluster control management, breakthroughs in power plant standardization management, and breakthroughs in photovoltaic power plant management.

All cascade hydropower stations of the Yellow River were properly scheduled for maintenance this spring, and artificial rainfall enhancement operations were carried out to further increase the water level of the cascade hydropower stations, increase the operating load rate, reduce the amount of air consumption, and improve the level of economic operation; at the same time, the conversion rate of the company's photovoltaic power plants was last year. The problem was not high. The company actively explored the management mode of new energy power plants, improved the installation and testing standards of photovoltaic power plants, and achieved a breakthrough in power generation. Photovoltaic power generation in April reached 64 million kilowatt-hours.

Since the beginning of this year, the Yellow River Company has placed "safety and multi-power generation" at the top of its work, and held two meetings of the power production coordination work leading group meeting and the safe multi-power generation seminar meeting twice a month to study the company's power production and power marketing strategies. Monthly power generation capacity of each power station, strengthen water forecasting and calculation, roll-out proposal proposals and strategies, and lead the power production coordination work team to actively coordinate with the grid company and the Yellow River Committee. Longyangxia reservoir discharge flow, the first quarter of Longyangxia Reservoir actual outflow of water 4.532 billion cubic meters, over the same period last year was 20.18%.

In addition, the Yellow River Company actively explores the operation and management experience of large generating units and photovoltaic power stations in high altitude areas, implements centralized control and optimized dispatching of cascaded power stations, strengthens dam safety testing, ensures the safe operation of cascaded power stations and photovoltaic power stations, and maintains safety and stability. In the production situation, five power stations maintained a long-term safety production record of more than 3,000 days, and two hydropower stations kept records of zero accidents since they were put into operation. At the same time, the company strengthened the maintenance of equipment, improved the health of equipment, and further changed the concept of safety in management. , Strengthen safety culture education, strengthen system construction, strictly implement responsibility assessment management, investigate major hazard sources, pay close attention to equipment defect management and safety management blind spots, and achieve steady improvement of safety production. The company's affiliated cascade power stations and photovoltaic power stations are the most important and stable power supply support for the Northwest Power Grid, providing green clean energy for the public for a long time.
