Problems solved by technology

However, to realize this function, the wind farm can only reduce the active power of its power generation by a certain percentage below the current power generation capacity, so as to reserve the rotating reserve capacity of the power grid to meet the needs of automatic power generation control of the power grid, but this will undoubtedly lead to a waste of wind power resources

Embodiment Construction

[0054] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0055] Such as figure 1 The invention provides an intelligent control system for active power of a clustered wind farm, the system includes a dispatching central station, a control master station, a control sub-station and a wind farm monitoring terminal connected bidirectionally in sequence; the dispatching central station monitors the entire wind farm; the The control master station issues control values ​​in real time; the dispatching central station sends the operation status, fault conditions and overload conditions of the line and key sections to the control master station and sub-stations of the system in real time; the wind farm monitoring terminal adjusts the wind power Field active power. Two-way data communication is used for control feedback between each layer, and the sub-stations of each layer formulate active power control schemes step by step...

Abstract

The invention provides an active power intelligent control system and an active power intelligent control method for a cluster wind farm. Stable and reliable operation of a power grid under various operation modes is guaranteed, the transmission capacity of the power grid and the acceptance capacity to wind power are improved to the greatest extent, meanwhile, intelligentization of a scheduling decision is realized, and a wind farm power generation plan is automatically calculated and issued, so that maximal effort of the wind farm is realized, miniaturization and optimization of a wind driven generating set under a condition that an accident occurs in the power grid are guaranteed, and the aim of fully utilizing new resources such as wind energy is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of renewable energy power generation and grid connection, and in particular relates to an intelligent control system and method for the active power of a cluster wind farm. Background technique [0002] As an important clean energy, wind power has the advantages of low development cost, small footprint and low secondary pollution to the environment, and has become one of the main means of replacing traditional petrochemical energy in countries all over the world. In recent years, as countries around the world attach importance to environmental protection, clean energy has developed very rapidly, and has shifted from the original decentralized development to large-scale centralized development. After decades of exploration, the development of clean energy in my country has developed rapidly in recent years, and has directly entered the development mode of cluster development, centralized intervention and long...
