Abstract

The invention discloses a draught fan group distributed power distribution control method considering communication delay and communication failures. The draught fan group distributed power distribution control method comprises the steps that the total output power of all draught fans and the total power required by all loads are collected in real time, and a high-performance controller is built; a distributed controller is built, the trace output power reference value of all the draught fans is obtained through the real-time output power of each draught fan and the output value of the high-performance controller, and the total power is rapidly and fairly distributed among all the draught fans; and draught fan output operates for the trace output power reference value according to the comparison of the actual wind speed and the rated wind speed through a variable rotational speed control method or a variable pitch control method. According to the draught fan group distributed power distribution control method considering the communication delay and the communication failures, the draught fan group total power is rapidly and fairly distributed among all the draught fans, and the communication delay and the communication failures are restrained.

Description

technical field

[0001] The invention relates to a power distribution method, in particular to a fan group distributed power distribution control method considering communication delay and failure. Background technique

[0002] As a way to optimize and integrate distributed power sources, microgrid is of great significance for reducing the burden on large power grids, improving power supply reliability, and improving the environment. As a renewable distributed energy source that is clean, environmentally friendly, abundant in reserves, and easy to develop, wind power generation systems have been widely used in microgrids. [3]-[4] . However, the addition of a large number of intermittent and fluctuating wind power systems makes the power balance within the microgrid and the power allocation among wind power systems very complicated. In addition, the increasing scale of the microgrid communication network puts forward higher requirements for the robustness of the control meth...
