- Abstract:
- This paper describes a method to detect temperature sensor faults in a district-heating substation (DHS). It uses valve position monitoring and variance monitoring to detect sensor faults. Depending on user requirements the method can be customized to either detect faults fast or to have a low false alarm rate and being able to detect smaller noise increases but at the expense of longer detection time. The result is a method that uses a limited amount of computing power, which does not require much computing precision since the only computing done is addition of integers and is therefore suitable for implementation in a microcontroller.
