Research On Centralized Monitoring System Of Wind Farm

With more and more attention paid to clean and environmentally friendly energy,wind power,as a kind of clean energy,has also been widely used in academic and industrial fields at home and abroad.In recent years,domestic investment in wind power related facilities is increasing.In order to manage the wind power network,many companies have established remote centralized monitoring system,which makes the management of wind power stations more detailed.Traditional wind power monitoring technology mainly uses virtual VPN network to manage wind power equipment,which needs to be set up on the public network.In the actual operation and operation,the mode is more and more unsuitable to the actual management of wind power plants because of the insufficient stability of data transmission,information interruption,security,remote control and other shortcomings.Based on the above problems,the author redesigned the remote monitoring system.Because there are many wind power companies in China,the late data collection of their monitoring system is the core problem.In this paper,the OPC interface is designed to collect data using a more standardized interface.After the data collection is completed,the data are converted and tested later.In addition,in view of the security of system information transmission in communication links,the system uses power dispatching data network to upload data and transmit instructions;in power data dispatching,independent network form is adopted to separate wind power related data and other networks;this form of network is advantageous.With MPLS/VPN network system,data can be transmitted by business message in the system,which effectively ensures that data can be delivered to the demander safely and quickly.It is of great significance for modern remote management.In order to improve the security performance of the system,the author considers the security of the system as a whole and the principle of fast and accurate data transmission.In the last part of the system design,the modern management of wind power generation system is realized from the front-end communication,real-time monitoring,remote monitoring and other links.In this paper,the overall system architecture design,data collection and transmission,power system security,remote control system design and other aspects are studied.The performance of the system has been further improved,the unmanned management of windfarms has been realized,and the management of wind power generation is more convenient and efficient.Rich theoretical significance and reference significance of monitoring practice in the field of wind power monitoring.
