Energy management control method and system of wind field

Abstract

The invention discloses an energy management control method and system of a wind field. The method comprises the following steps of acquiring a running state and a control state of each machine set in the wind field; acquiring active power, reactive power and a wind speed of each machine set, and calculating numerical values of preset parameters according to the active power, the reactive power and the wind speed; receiving an active power output control command of the wind field, carrying out active power control of the wind field according to a preset active power control algorithm and the numerical value of the corresponding preset parameter; receiving a reactive power output control command of the wind field, and carrying out reactive power control of the wind field according to a preset reactive power control algorithm and the numerical value of the corresponding preset parameter; and carrying out control on starting and stopping of the machine set in the wind field according to a preset wind field starting and stopping control algorithm and the numerical value of the corresponding preset parameter. By the method and the system, high-standard control on the energy of the wind and power field can be fulfilled.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a control method and system for wind farm energy management. Background technique [0002] In recent years, wind power has become one of the fastest growing clean energy in China and the world. The large-scale use of thermal power generation and private cars has caused great pollution to the domestic environment. Therefore, it is urgent to vigorously develop clean energy and change the energy structure of our country. Wind power technology is more mature and cleaner than solar power, tidal power or nuclear power, and has been favored. [0003] With the increase in the number and scale of wind farms, and the increasing capacity of wind turbines, the importance of wind farm management systems for the operation and management of wind farms has become increasingly apparent. However, the core control technology of wind power generation has always been in the hands of foreign com...

AI Technical Summary

Problems solved by technology

The way of wind power generation is different from thermal power and hydropower. Wind power generation depends on the wind, and the wind is changing all the time. The change of wind direction or wind speed will have a great impact on the power of the unit, especially the domestic wind power unit. The failure rate, the unpredictable wind will make the unit often report a failure and stop
