Method for Improving Reporting of Operational Data of a Wind Turbine

Abstract

The invention relates to a method for improving reporting of operational data of a wind turbine during operation thereof; said method comprising the steps of:allowing an array of sensors to sense one or more specific parameter values of said wind turbine during operation thereof;in respect of one or more sensors, transmitting said parameter value being sensed to a control system;allowing said control system to register a critical event in case a sensed parameter value, or a combination of two or more sensed parameter values, represents a situation in which it is desired to shut down the wind turbine according to one or more predetermined criteria;allowing said control system to set a specific alarm at a point in time at which a specific critical event is registered; and allowing said control system to reset said specific alarm at a point in time at which the registration of the presence of said critical event ceases; wherein each specific alarm is associated with a corresponding alarm ID;wherein said alarms IDs are grouped into different sectors; each sector belongs to a specific part of the wind turbine or its installation or operation;wherein information from said control system relating to settings and resetting of one or more alarms corresponding to an individual alarm ID is being transmitted to a monitoring system which is configured for logging and storing such information;wherein said method furthermore comprises the steps of:i) in respect of one or more alarm IDs, allowing said monitoring system to register a time stamp in respect of each setting of said alarm ID and to register a time stamp in respect of each resetting of said alarm ID;ii) in respect of a specific sector, allowing said control system to count the amount of time at which no alarm IDs belonging to that specific sector is set, and to transfer information relating to such counting to said monitoring system;iii) in case the monitoring system detects that counting in step ii) has stopped in respect of a time range at which no alarms belonging to that specific sector is logged as being set, allow the monitoring system to register that the wind turbine in respect of said specific sector is not operating properly in a period of time corresponding to that range in time.

Benefits of technology

The present invention aims to enhance the monitoring of operational data of a wind turbine during operation. The invention allows the control system to count the amount of time no alarm IDs are set in a specific sector and transfer the information related to this counting to the monitoring system. This improves the reporting of operational data and helps to better manage the wind turbine during operation. Overall, the invention contributes to the efficient operation and maintenance of wind turbines.

Problems solved by technology

Now, it may happen that the data received and / or registered by the monitoring system from the control system and relating to the setting and resetting of various alarm IDs and their associated time stamps, indicating the point in time of such settings and resettings of alarms, are not representing an accurate picture of the operational state of the wind turbine.

One reason for such an inaccurate picture of the operational state of the wind turbine may be due to a transmission error between the control unit (receiving the parameters measured by the sensors) and the operational monitoring system storing the associated data.

It is clear that an incorrect picture of an operational state of a wind turbine, as determined by the monitoring system will lead to an allocation of the value represented by the power produced by a wind turbine between the manufacturer and the operator in a way which deviates from the true situation and thereby also does not comply with the original intention as stipulated by the contract agreed between the operator and the manufacturer of the wind turbine.
