7.5 Transfer
The data and status messages supplied by the wind energy converter can be transferred by fax, telephone (modem), SMS and various pager systems. As soon as a turbine shuts down because of a malfunction, several fault messages can be sent to up to four receivers.
7.5.1 Fault message to central monitoring system (office computer)
In case of a fault message, the data listed above (see 7.4) are transferred via the windfarm monitoring system to the central monitoring system at the Service station.
If the owner is also connected to the monitoring system, he will also receive the message.
7.5.2 Fault message to fax
All fault messages that are send to a PC can also be sent to a fax.
7.5.3 Fault message to SMS or pager (city call)
The program provides the possibility to connect to the City Call of German Telekom.
The City Call number is then dialled by the central computer or the windfarm computer directly after having received the fault message. The City Call can either be activated without sending any further data or it may include transmission of a numerical fault code.
7.6 Control
The following parameters can be controlled by the central computer of the monitoring system:
Start or stop of the windfarm
(maximum) power output of the individual or the turbine windfarm (in case there is a power / voltage control system for the substation)
power gradient (change of power output as a function of time) for starting and stopping routines of the windfarm or the individual turbine).
7.7 Other functions
If an automatic data request could not be completed successfully (e.g. due to a bad telephone line), the missing data of the respective day can be requested manually and then included in the data processing subsequently. A transfer protocol (protocol of modem connections) can also be provided.
7.7.1 Transfer protocol
At each attempt to establish a connection, the transfer protocol registers the windfarm number, date, time, type of connection and the data transfer. With automatic data requests, only failed attempts are registered and colour-marked in the protocol.
The transfer protocol always lists the last 120 messages.
