ONITORING
Individual ENERCON wind energy converters or windfarms (see figure 16) are equipped with a remote monitoring and control system. With individual wind energy converters this system is installed near the control cabinet or in the substation, in windfarms it is normally installed in the substation. The hardware required for the remote monitoring is a standard PC configuration. ENERCON Service provides a central remote monitoring system which polls the individual wind energy converters and windfarms to obtain current operating data, allows to change turbine parameters by remote control and receives fault signals and warnings.
Please not, that the operation single wind turbines as well as wind farms are able to operate without the wind farm monitoring system. The remote monitoring system is not part of the control system of the wind energy converters.

Figure 16: Remote monitoring system for windfarms
On windfarms, the turbine data are transmitted to a PC (windfarm computer) by means of a short-distance modem. The windfarm program collects the data of the individual wind energy converters. Windfarms are equipped with communication lines which connect each wind energy converter with the remote monitoring system.
The PC is provided with a modem for the telephone network to be able to communicate with other computers.
From the remote monitoring system at the wind energy converter or on the windfarm, current operating data are transmitted to the central monitoring system
