Description

Technical Field

[0001] The present invention relates to a circuit breaker monitoring system, a circuit breaker monitoring method, a circuit breaker vibration data generator, a circuit breaker vibration data generation method, and a computer program unit / computer program unit. Background Art

[0002] The operating mechanism of a circuit breaker is one of the main subsystems in a switchgear / power distribution device that is prone to failures. Most mechanical fault modes in the mechanism can be detected by monitoring the travel curve representing the position of the moving contact. In addition, the travel curve can also reveal electrical fault modes, such as contact ablation.

[0003] Currently, the gold standard for condition monitoring and diagnosis of a circuit breaker (CB) operating mechanism is the use of travel curve measurement. For medium-voltage circuit breakers, the travel curve is measured by position sensors on the main shaft of the operating mechanism or on a push rod connected to three electrodes. Optionally, a speed sensor or even an accelerometer can be used to transform the measured sensor signal into displacement describing the travel curve through integration.

[0004] In a laboratory environment with less impact from cost and other practical issues, this setup can provide the best results and can be used to generate training data for machine learning or threshold-based algorithms.

[0005] However, it is not always practical to use travel curves on a larger scale in the field. Therefore, today, travel curve monitoring is rarely applied to switchgear in the field due to reasons related to cost, limited space, and sensor life.

[0006] It is necessary to solve these problems. Summary of the Invention

[0185] In one example, in at least a portion of the plurality of reference closing operations of at least one reference circuit breaker, at least some of the plurality of stroke curve data of the movable contact relative to the fixed contact are synthetically generated.

[0186] A related method for generating vibration data of a circuit breaker includes:

[0187] - Providing, by an input unit, to a processing unit, a plurality of stroke curve data of a movable contact relative to a fixed contact in at least a portion of a plurality of reference opening operations of at least one reference circuit breaker, and a plurality of timing vibration data in at least a portion of a plurality of reference opening operations of at least one reference circuit breaker, wherein at least a portion of the reference opening operations includes: the movement of the movable contact away from the fixed contact, and the plurality of timing vibration data are acquired by at least one vibration sensor mounted to at least one reference circuit breaker;

[0191] - Outputting, by an output unit, the sample timing vibration data in at least a portion of an opening operation of the exemplary circuit breaker.

[0192] In one example, at least a portion of the opening operation of the sample circuit breaker is the same as at least a portion of the multiple reference opening operations of at least one reference circuit breaker.

[0193] In one example, the multiple stroke curve data of the movable contact relative to the fixed contact of the multiple reference opening operations of at least one reference circuit breaker includes data on the displacement of the movable contact relative to the fixed contact over time, and the stroke curve data of the movable contact relative to the fixed contact of the opening operation of the sample circuit breaker includes data on the displacement of the movable contact relative to the fixed contact over time.

[0196] In one example, in at least a portion of the multiple reference opening operations of at least one reference circuit breaker, at least some of the multiple stroke curve data of the movable contact relative to the fixed contact are synthetically generated.

[0197] Now refer Figures 3 - 5 , to more specifically and in detail describe a circuit breaker monitoring system, a circuit breaker monitoring method, a circuit breaker vibration data generator, and a circuit breaker vibration data generation method.

[0198] Accordingly, the inventors recognized that they could apply methods of artificial intelligence (AI) to transform circuit breaker stroke curve data from a laboratory and other previous setups into vibration data corresponding to the same fault mode or health state. This enables the creation of synthetic training data. The inventors also recognized that such a transformation can actually be used in a trained machine learning algorithm - such as a neural network trained based on stroke curve data and vibration data - which, when presented with vibration data of a circuit breaker in the field, can actually determine the health state of the circuit breaker - as if the stroke curve had been acquired, but using a simpler method of acquiring vibration data.

[0199] The starting point of the inventors was that: stroke curve sensor data is a good indicator of faults, but it is difficult to implement in the field. Therefore, new technologies were developed to address this issue.

[0200] In addition, the inventors recognized that there is a relatively large amount of available laboratory travel curve data from durability tests, as well as associated vibration data. However, for model training and the like, it is more preferable to utilize travel curve data and associated vibration data regarding the correct operation of the circuit breaker and the presence of various defects. Synthetic travel curve data can be generated through simulation, for example, by using standard multibody simulation methods and finite element simulation methods to calculate. However, considering wave propagation in all mechanical components connected, for example, by joints and bearings, the calculation of vibration caused by impacts requires more complex methods. Therefore, the new technology can also more easily generate synthetic vibration data, which can then be used, for example, in system models.

[0201] Therefore, the new technology enables the available real and synthetic travel curve data to be used for training a machine learning model that will not receive the same type of sensor data but will receive data such as vibration data.

[0202] Figure 3 A detailed example of the training and operation of a sample circuit breaker vibration data generator is shown.

[0203] Here, different sensors (such as vibration sensors) - which are different from the sensors used to obtain travel curve data - are used to obtain data that is also used, along with an existing corpus of travel curve data, to augment the training dataset. A sequence-to-sequence model (referred to as model T in Figure 3 ), can then transform the travel curve data into corresponding data (vibration data) from other sensors.

[0204] Based on the existing data of travel curves and vibration data (or other sensor data) collected from experiments, a sequence-to-sequence model is trained. When exposed to new, previously unseen travel curve data, the model is able to generate the corresponding data of another sensor. The model (model T) can be trained unsupervised. However, data from healthy and faulty conditions is utilized in the training data. The accuracy of the method is evaluated using some accuracy metrics, such as the mean square error or Manhattan distance of all samples used in training and testing.

[0205] The output of model T, that is, other sensor data (OSD), can have various forms. It can be raw vibration data, but it can also be the signal envelope or its frequency domain / frequency range. It can be specific features of the data, such as peaks, change points, or values at specific frequencies. Other sensor signals are also possible.

[0206] This is what vibration data and other sensor data mean.

[0207] Figure 4Shows a detailed example of the operation of an exemplary circuit breaker vibration data generator.

[0208] Then, as Figure 4 shown, when training the model T, it is used to increase the training data of the machine learning (ML) algorithm (see Figure 4 ). During this process, the existing stroke curve data (labeled as healthy / faulty for some applications) can be used to generate additional training data. In addition, simulated stroke curves (from standard multibody simulation methods, finite element simulation methods, or other techniques) can be used to obtain other sensor data that cannot be realistically generated by simulation. As a result, the available training data consists of sensor data measured in reality and examples synthetically generated by the model T.

[0209] In addition, an ML algorithm can be trained based on the stroke curve data and vibration data. As described above, when vibration data from a circuit breaker is provided on-site, the ML algorithm can determine the operational health status of the circuit breaker, such as correct operation or faulty, and even determine the type of fault based on this vibration data. Vibration data is easier to sense from a circuit breaker and is of course simpler than the data required to determine the stroke curve data, but the diagnostic ability is as good as if the stroke curve data had been obtained and used to evaluate the health of the circuit breaker.

[0210] Figure 5 Shows a schematic diagram of how to utilize the generated data.

[0211] As described above, the new technology can be used for different scenarios that are most likely to follow the Figure 5 shown pattern. The model T is used to ensure the availability of the maximum amount of training data by "converting" the available stroke curve data into data of the sensor types used. The new augmented training data set can be used for a series of models, including but not limited to:

[0212] · Classifiers for detecting healthy and faulty states

[0213] · Anomaly detection algorithms

[0214] · Future state prediction

[0215] · Identification and location of fault modes

[0216] · Fault prediction, for example, by means of remaining useful life estimation.
