A regional available solar energy resource evaluation method comprises the following steps: collecting basic data of a to-be-evaluated region; quantizing everyday available solar energy radiant quantity in the region; quantizing photovoltaic optimal allocation quantity in the region. The regional available solar energy resource evaluation method can calculate everyday available solar energy radiant quantity in the region according to regional geography weather information like longitude and latitude and sunlight intensity; the method then considers regional photovoltaic construction land occupation conditions in the region according to the everyday available solar energy radiant quantity, thus using economical purpose to determine the best photovoltaic installed capacity. The calculation evaluation method and analysis evaluation system can ensure the installed photovoltaic to maximumly fully utilize everyday available solar energy radiant quantity in the region to generate power, thus preventing investment waste caused by idle photovoltaic after excessive construction of photovoltaic capacity, and providing planning suggestions for regional grid and power source construction.

A yaw control system and yaw method based on the effective damping of frequency converters belong to the technical field of wind power generation. The yaw system includes a main control controller, at least one set of yaw motors, a frequency converter connected to the yaw motors, a braking system, a position encoder, and an uncable protector, and the set of yaw motors is four , 3 of which are yaw driving motors, and 1 is a yaw damping motor during the start and stop process. Each frequency converter drives each yaw motor independently. On the yaw ring gear, each frequency converter, uncable protector, and position encoder are respectively connected to the main controller. The invention adopts the frequency converter to drive the yaw motor, which can realize the soft start and soft stop of the yaw system, reduce the impact of the starting current on the motor, make the fan run smoothly, prolong the life of the motor, and reduce the damage caused by the vibration of the fan; The yaw system can also realize the speed regulation operation of the yaw.
