Distributed fan locating and sizing system

The invention discloses a distributed fan locating and sizing system, which belongs to the technical field of wind power plant micro locating. The distributed fan locating and sizing system comprises a fan locating constraint controller, a running state detector and a result output device, wherein the fan locating constraint controller is used for generating a fan locating constraint and outputting a fan field control target according to the quantity, positions and capacities of fans in a fan field; the running state detector is used for calculating and monitoring the running state, stable running state or unstable running state of a power system after a distributed fan is connected to a power distribution network according to power flow; and the result output device is used for adopting a node to be selected for installing a fan resolved on the basis of a penalty function-ant colony algorithm, the capacity of the fan arranged on the node to be selected and an optimal path through which the fan is arranged according to the output of a control target optimizer. According to the system, a constraint processing technique and an intelligent optimization algorithm are combined, so that the defects of running instability and difficulty in obtaining better optimizing results existing in the conventional intelligent optimization algorithm are overcome, and the result of distributed wind power micro locating can be better output finally.
