Description

Energy storage frequency modulation system network architecture for thermal power plant Technical Field The utility model belongs to the technical field of power generation control, and particularly discloses an energy storage frequency modulation system network architecture for a thermal power plant. Background In the field of modern power production, along with the increasingly strict regulation of energy structures and environmental protection requirements, power plant operation faces a plurality of challenges, and energy storage regulation and flue gas monitoring technologies play a key role in the challenges, but the energy storage regulation and the flue gas monitoring technologies are not integrated with each other and cannot be regulated in a cooperative manner due to the fact that the management and control network architecture of the existing thermal power plant is not integrated. The energy storage system is used as a key support technology, can store electric energy in low electricity consumption valleys, release electric energy in electricity consumption peaks, realize load balance, relieve power grid pressure, stably operate in cooperation with a traditional power supply, improve system efficiency, reduce fluctuation influence through prediction and regulation, meet grid connection requirements, provide quick power support in emergency, and improve system stability. However, the current application of the energy storage system in the power plant only simply considers the storage and release of the electric power to deal with the load change of the power grid, and the energy storage system is not closely related to other key production links of the power plant, so that the cooperative optimization degree is low. Regarding flue gas monitoring, flue gas discharged by a coal-fired power plant contains smoke dust, carbon dioxide, sulfur dioxide, nitrogen oxides and a small amount of carbon monoxide, the smoke dust directly influences the environmental quality of the atmosphere, and the carbon dioxide, the sulfur dioxide, the nitrogen oxides and the like are all acid gases and are main factors for forming acid rain. The CEMS flue gas emission continuous monitoring system can monitor pollutants such as sulfur dioxide, particulate matters, carbon monoxide, carbon dioxide and the like in real time, plays an important role in monitoring the pollutant emission of a thermal power plant, and is mainly applied to monitoring of desulfurization engineering and monitoring of the pollutant emission process. However, the existing flue gas monitoring system mainly focuses on the acquisition of pollutant emission data so as to meet the environmental protection supervision requirement, and has very limited application to the whole production optimization of the power plant for monitoring data, especially in the aspect of cooperation with energy storage adjustment. In summary, the energy storage regulation and the flue gas monitoring technologies in the current power plant are operated independently, and no organic combination is formed. On one hand, the energy storage system can not utilize the power plant operation condition information reflected by the flue gas monitoring to optimize the charging and discharging strategy and the operation mode of the energy storage system, and can not further improve the comprehensive benefit of the energy storage system to the power plant production, on the other hand, the flue gas monitoring data are only used for meeting the environment-friendly compliance, and do not perform data interaction and collaborative decision with the energy storage regulation from the aspects of comprehensive management and efficient utilization of the power plant energy, so that the dual optimization of the power plant on energy utilization and environmental protection is realized. Therefore, a power plant management and control network architecture combining energy storage regulation and flue gas monitoring is needed to improve the overall operation efficiency and environmental protection level of the power plant. Disclosure of utility model In order to solve the technical problems listed in the background technology, the utility model provides a network architecture of an energy storage frequency modulation system for a thermal power plant. The specific technical scheme is as follows: The energy storage frequency modulation system network architecture for the thermal power plant comprises a management and control layer and a field layer, wherein the management and control layer comprises an application Ethernet layer and a control Ethernet layer which are formed by interconnection of computers, the field layer comprises an energy storage frequency modulation system and a flue gas online monitoring system which are formed by interconnection of field devices and computer networking, the control Ethernet layer and the application Ethernet layer realize data sharing through a server, a frequency modu
