9、ystem (temperature, dust, EMC) Lower costs,Setup with PC in the turbine More flexibility because of variable software design Higher conditioning power Data redundancy (Controller + PC) More communication possibilities,Saving of Data,Saving of Data,Setup without PC in the turbine Signal conditioning

10、and data memory raw data recorded with 100 Hz calculation of the statistical values definition of the memory sections dynamic data 10 ms meteorological data 1 sec statistical data 10 min Memory capacity with100 channels at 100 Hz internal flash 4 Gbyte: 27 hours external HDD 1000 Gbyte: 28 days inco

11、mming amount of data 40 kbyte/sec In case the external medium will be changed the internal memory will be used automatically and after availability the data will be transfered.,Saving of Data,Setup with PC in the turbine,Conditioning and saving of the data using the server software test.node Test Co

12、ntroller provide the raw data Server Software test.node records the data synchronizes from one or more device calculation of the statistical values saving the data on a PC or in a data base (SQL) Online convertion of the binary data e.g. into FAMOS or MATLAB Visualization of the online- or the saved

13、 Data The saving of the data device or PC could happen redundancy.,Saving of Data,test.node,Saving of Data,Secure the memory function also with failing PC,Remote Reboot,Remote Reboot,Not everywhere it is easy to reach the turbine complete system can be rebooted without personnel whole system starts

14、working within 10 sec server software starts with adequate PC-configuration (auto start),Alarm Management,In case of not acceptable situations speed to high wind turbulences, unexpeted material stress others alarm will be released and mail will be send (FTP client, e-Mail.),Synchronized Recording in

15、 a Wind Park,The Measurement system can be synchronized using different media time signal, z. B. DCF77, IRIG over RS485, accuracy approx. 100 ms GPS signal, NMEA over RS232,accuracy approx. 0,2 s - 1 s SNTP over Ethernet (time server), accuracy depends on network load in case it is possible to connect the controller via RS485 together, an accuracy of +/- 2 s is possible.,Partner a
