Artificial Intelligence

Since the automation of industrial plants, extensive process data has been determined and recorded. With methods of artificial intelligence, especially machine and deep learning, we create data-driven models from your operating data. These fulfil a wide range of application purposes, support your employees in operation and comprehensibly increase the efficiency of your plant.

Use case prediction of power consumption

In district heating networks, the energy demand must be covered at all times. In biomass (heating) power plants, the biomass boiler often cannot react quickly enough to fluctuations in demand and peak loads. In order to be able to meet the demand, a fossil fuel-fired peak load boiler is usually used. On the one hand, this is cost-intensive and, on the other, causes high emissions. With appropriate control, it is also possible to react to power peaks with the help of a buffer storage tank.

At VWE, we use neural networks to predict the future heat demand of your district heating networks. The specifically adapted model uses historical data and other parameters (e.g. outside temperature) to calculate the expected power consumption. This prediction enables you to optimally use the buffer storage tank and reduces the operating time of the peak load boiler. In addition, your biomass boiler is operated more consistently and more quietly.

Use case measured value validation

The validation of measured values is essential to ensure the efficient operation of an automated system. Sensor failures and incorrect readings lead to suboptimal control and thus inefficiency. Artificial intelligence enables the validation of measured values without the use of additional hardware in the form of redundant sensors.

For example, a VWE regression model based on artificial intelligence is used to validate the measured value of an O2 probe. The residual oxygen content measured with this probe is the most important source of information for combustion control. Accordingly, the correction of an incorrect measured value – for example due to a drifting sensor – is of great importance.

VWE also works with a neural network for calculating the boiler output, which is trained with purely flue gas-related input data (independent of the water side). This enables the bridging of short heat meter failures or the validation of the sensor output value.
