Thermal power plant plant-level load optimal distribution system based on plant and power grid coordination

Abstract

The invention discloses a thermal power plant plant-level load optimal distribution system based on plant and power grid coordination. The thermal power plant plant-level load optimal distribution system based on plant and power grid coordination comprises a network firewall, a master station compute server, a master station application server, a reverse isolation device, a non-real-time VPN and a substation application server, wherein the master station compute server is arranged in a power grid safe area II, and is in two-way connection with an energy management system in a power grid safe area I through the network firewall and a data communication network, the master station compute server is in two-way connection with the master station application server in the power grid safe area II so that service data exchange can be achieved, a master station coal consumption system in a power grid safe area III transmits the service data to the master station application server in a single-way mode through the reverses isolation device, and meanwhile, two-way communication is carried out between the master station application server and the substation application server arranged in the power grid safe area II through the non-real-time VPN so that uploading operation and issuing operation of the service data can be achieved. According to the thermal power plant plant-level load optimal distribution system based on plant and power grid coordination, optimal distribution of the load of the whole plant can be achieved, and the purpose of safe and economical operation can be achieved.

Description

technical field [0001] The invention belongs to the field of energy-saving power generation dispatching in the electric power industry, in particular to a plant-level load optimization distribution system for thermal power plants based on plant-network coordination. Background technique [0002] With the vigorous promotion of energy conservation and emission reduction in all walks of life, the power industry, which provides important energy support for the national economy, is also facing the requirements of energy conservation and consumption reduction. Energy-saving power generation scheduling has not only received strong support from policies in recent years, but also has achieved substantial breakthroughs in specific applications. Arranging power generation plans according to the actual energy consumption level of thermal power units is one of the typical applications. According to domestic and foreign statistical data, the optimal distribution of plant-level loads can s...

Problems solved by technology

This dispatching method has played a positive and effective role in promoting the safe and stable operation of the power grid. However, because the current load dispatching method does not consider the economic differences between units and the actual production and operation status of the units, it does not implement each unit in the power plant. The optimal economic load distribution of the unit affects the operating life and maintenance cost of the generator set to a certain extent, and cannot meet the requirements of the current low-carbon economy and energy conservation and emission reduction policies
