Problems solved by technology

For example, in the alarm function, the classification standard of the target item level of each event under the status code is not clear, and there are few integrated processing methods for the alarm function of the status code that comprehensively consider events and accidents; In wave method, seldom consider capturing important relevant parameter information and improving program execution efficiency at the same time, which is very unfavorable for accident analysis of wind turbines after accidents. Therefore, the main control system is designed for the realization of wind turbine alarm function Optimization has strong practical significance

Embodiment 1

[0065] After determining the status code initialization parameter information, follow the figure 1 The steps shown make an alarm determination on the status code. As shown in step 101, after the scan cycle time arrives, go to step 102 to determine whether the event sequence number is within the set interval, if it is, go to step 103, otherwise go to step 114 and consider that the event sequence number ID exceeds the limit and then proceed to step 116;

[0066] Continue step 103, initialize the status code (that is, load the status code predefined information) and then go to step 104, if the status code is enabled and the shielding state is disabled, then go to step 107, otherwise go to step 105;

[0067] Continue step 105, after judging that the status code is in the active state but the masking state is also active, go to step 106 to reset the status code, otherwise go to step 116;

[0068] Continue step 107, after judging that the input parameter falls within the trigger in...

Abstract

The invention discloses an alarm optimization design method for a main control system of a wind turbine. A multi-dimensional status code is used to realize the hierarchical alarm function of the operating state of the unit equipment. The multi-dimensional status code is divided into an event status code and an accident status code. Triggering and automatic reset function, according to the input parameters and initialization parameters, the logic criterion operation is performed to determine the automatic activation and reset of the status code, and it is provided for other functional modes of the main control system. When the status code event that meets the set level conditions is activated, a fault recording method based on rolling update of the sliding window of the ring buffer is used to automatically capture the values ​​of the operating parameters within the width of the target time section before and after the accident, and store them as files for the unit to recall the accident. use. The invention fully considers the attributes of the multi-dimensional state code, realizes the safe operation of the wind turbine under unattended conditions, is stable and reliable, and is easy to implement and deploy.

Description

technical field [0001] The invention belongs to the technical field of wind turbine control, and in particular relates to an alarm optimization design method for a main control system of a wind turbine. Background technique [0002] Wind power generation is the main form of utilization of wind energy, a clean and renewable energy source, and permanent magnet direct-drive fans are the main installed form of large-capacity wind turbines. At present, relevant researches have been carried out on the design and development of the main control system of the permanent magnet direct-drive fan at home and abroad, but there are still some problems. For example, in the alarm function, the classification standard of the target item level of each event under the status code is not clear, and there are few integrated processing methods for the status code alarm function that comprehensively considers events and accidents; when designing the accident snapshot and fault record when the wind...
