    Abstract: Wind power and photovoltaic power generation are developing rapidly, and installed capacity accounts for an increasing proportion of the power system. However, most new energy power stations are not equipped with energy storage equipment. Wind power and photovoltaic power generation do not yet have primary frequency modulation capabilities. For a long time in the future, the participation of thermal power generation in primary frequency modulation will still be the main method of primary frequency modulation in my country. The primary frequency regulation capacity of the combined heat and power unit often fails to meet the requirements due to heating. This article takes a 650MW thermal power heating unit as an example, and optimizes the primary frequency regulation of the unit. After optimization, the primary frequency regulation capacity of the unit is greatly improved. The optimization method in this paper has certain guiding significance for the optimization of primary frequency regulation of other heating units.

    Abstract: The oxygenate water level is an important adjustment parameter in the operation of the fire generator set, and the water level may result in the safety of the water pump. The high water level will not only affect the oxygen effect, but it is also possible to cause the water shot to the steam turbine to cause a water shot or give the water tank full water, oxygenate vibration, drain and vapor with water. When the load is low (generally 35% rated load), the oxygenate water level is controlled by large and small valve, condensate pump variable frequency control condensed water drum pressure. When the unit load is high (greater than 35 rated load), the oxygenate water level is controlled by the condensed water pump, the large valve and small valve controls condensed water drum pressure.

    Abstract: Shandong Power Grid is about to achieve the development goal of 30% of new energy power generation installed capacity, 30% of foreign power input into Shandong, and 30% of thermal power installed capacity. Neither new energy power generation nor external power has the ability to adjust primary frequency. Thermal power is the main force of primary frequency modulation of Shandong Power Grid. This article counts all primary frequency modulation remote tests of the Shandong Power Grid in 2020, analyzes the current status of Shandong Power Grid’s primary frequency modulation, gives an assessment method for the primary frequency modulation integral power, and summarizes three reasons for the unqualified primary frequency modulation. The reasons are analyzed separately, and optimization suggestions are given.
