5.      System main function

5.1   Data Acquisition, Exchange and Storage

The system collect all kinds of equipment real-time data of fan control system and substation system, and transmit to the remote monitoring center data servers in real-time. With each unit after processing release and exchange, the data storage to the real time database, to provide support for the later data statistics and analysis.

5.2   Video Monitoring

The system gets wind power station wind farms real-time image through the camera. The operators can also in remote control field camera rotate, stretching action, and to realize the global or local fan detailed check. System can give out sound and light alarm, record and report the officer immediately when the unusual situations happen.

5.3 Real-time monitoring of production and operation status

the system is real-time monitoring the total real-time load, the operating conditions and real-time load of the each wind farm, and the real-time operating status of each wind turbine. Real-time monitoring of the production status is displayed by topographic maps, icons, list, as well as multiple ways for the expression of real-time information and data display.

5.4 Data manually input

Some information can not be achieved automatically collected data such as average wind speed, the planned generating capacity, unplanned standstill reasons, unit failure or maintenance, and other information, the system provides manually input of data, mainly used for part of the fault information entry unit, part of the statistical data, other non-real-time data collection information.

5.5 Production control

As wind farms are built in remote areas, site unattended, fewer people on duty, remote monitoring and control is the current trend. The remote control is first transmitted the real-time data such as wind farm wind turbine, booster station energy metering equipment, and so on to the control center. And then based on these real-time operating data, the central control center is testing and remote controlling for wind farm booster station electrical equipment state, detecting and controlling the wind turbine state such as starting ,stopping, resetting, adjusting the output. The development of remote control functions based on the system of the booster station and fan monitoring system open communication interface and accurate acceptance and processing the signals sent by the centralized control center.

5.6 Wind power prediction

According to the interface Statute (Statute for the OPC) identified in consultation with the manufacturers of wind power prediction system, ensured accurate communication with the wind power prediction system, wind power prediction is completely and accurately incorporated into the remote control center system.

5.7 Comprehensive statistics of the wind farm

Wind farm of comprehensive statistical information completed the operation, monitoring and real-time display each geographic segment of the electric field profile, the general situation of the electric field, electric field, the overall installed capacity, real-time active power, real-time reactive power, the number of installed units, run number, power generation, grid electricity, wind speed. So production management personnel can keep abreast of the overall production and operation of the wind farm.

5.8 Statistical reporting and analysis

The system can be integrated processing, statistical analysis, automatic generation of a variety of production report for production data, Statistical analysis such as power generation, grid electricity, the net power, wind speed, temperature, plant power consumption rate, operation rate, the equivalent of full capacity utilization data, for economic indicators and the main operating parameters, for users to query and print. The system can automatically generate day, month, annual report.

5.9 Production curve and the trend

One of the characteristics of wind power is the instability of the wind source. As the wind speed changes, the system controller will adjust the state of the wind turbine accordingly, and change the various system variables accompanied. Variable changes in a intuitive and concise method of trend curve analysis. The trend curve is both intuitive and simple method to analysis of the variables changes.

5.10 Statistics and Analysis of wind farm operation indicators

The corporate headquarters of wind power statistics under the wind farm safety performance indicators, business performance indicators, production targets, the natural characteristics of the index, reliability index, power index, wear and tear indicators, operation and maintenance capacity indicators, can provide the basis of objective scientific data selection for the company's performance appraisal and new wind farm equipment.

5.11 Wind farm on the benchmarking management

The objective is the wind farm operation indicators to gauge the distance comparison benchmark. The process of implementation of benchmarking management can identify problems of production and operation that not easily be found, and raise corrective actions targeted, and continuously improve the management level and economic benefits of wind power  company. The system determines the optimal fan as a fan can use a maximum number of hours at each wind farm,
5.12 System permissions management

The system has powerful rights management, authentication features, different permissions can be customized for different levels of users, and any operation of each user are strictly log records to track, many ways to ensure that the system does not to be accessed and manipulated by unauthorized users.

5.13 Statistics and Analysis of wind farm equipment failures

When the equipment running status changes or parameters beyond the set limits, the system can record the exceptions occurred and issued a warning in a timely manner to report on duty, automatic statistics to the number and mode of fan failure in the wind farm, based on the real-time upload the fault signals from wind farms. Analyze the relationship of each subsystem failure and the unit power generation and stop. The results of the analysis can be used as the spare parts management of wind farm, unit maintenance and repair, and provide some guidance to personnel operating.
