All wind turbines are connected to the upper computer operator station of the main control room through fiber optic Ethernet to realize remote monitoring of the entire wind farm. The upper computer monitoring software should have the following functions:
1 system has a friendly control interface. When preparing the monitoring software, fully consider the requirements of wind farm operation management, use the Chinese menu to make the operation simple, and provide convenience for the management of the wind farm as much as possible.
2 The system displays the operation data of each unit, such as the instantaneous power generation, cumulative power generation, power generation hours, wind turbine and motor speed, wind speed, wind direction, etc. of each unit, and transfers the data of the lower unit to the upper computer. It is displayed on the display and can be visually displayed in the form of a curve or a chart if necessary.
3 The system displays the operating status of each wind turbine, such as starting, stopping, steering, hand/automatic control, and large/small generator operation. The status of the wind farm is used to understand the operation of the entire wind farm.
4 The system can display the faults occurring during the operation of each unit in time. When the fault is displayed, the type of fault and the time of occurrence can be displayed, so that the operator can timely handle and eliminate the fault, and ensure the safety and continuous operation of the wind turbine.
5 system can achieve centralized control of wind turbines. In the centralized control room, the duty officer can change the setting state and control the lower position machine only by operating the corresponding key indicating a certain function. Such as power on, stop and left and right direction. However, such operations have certain authority to ensure the safe operation of the entire wind farm.
6 system management. The monitoring software has the function of timed printing and manual instant printing of running data and automatic fault recording, so that the history of the wind farm operation status can be checked at any time.
