Advanced Applications: Renewable Energy
The liberalisation of energy markets has led to an increase in renewable energies. The growth in this field is further enhanced by legal requirements, such as the laws governing CHP generation and renewable energies (KWK and EEG laws in Germany), and by financial incentives to promote these forms of energy.
Currently, the principal provider of green electricity are wind farms. However, special requirements have to be met when connecting wind farms to the power grids of local energy suppliers, namely a high availability and, on the other hand, fulfilment of the special requirements governing energy infeeds exceeding the base load supply.
For the control, visualisation and monitoring of mean-voltage and high-voltage switchgear, the modular station automation system IDS SAS is available. The highest hierarchical level consists of central service control stations where all information from the connected wind parks is collected and where HIGH-LEIT is in charge of operations control.
The different wind farms can be addressed e.g via telephone connection (modem/ISDN). After addressing from the central control room, the operator is informed about the current status of the wind farm, enabling him to intervene on site, if necessary.
Another main focus in the operation of wind farms is to ensure and to monitor the status of the wind farms and their maintenance.
The maintenance tool ACOS OM monitors the cycles of manual interventions into system components, enabling the evaluation of results in accordance with the rules of an expert system. For this purpose, the measured values acquired in the diagnostic process, as well as automatically transmitted measured values from the control systems or the status monitoring systems of the evaluation kernel, are evaluated by a station evaluation function. The parameterisation of the evaluation kernel and the definition of evaluation limits takes can be conveniently done via input dialogues.
