We present a novel approach to detecting leaking reciprocating compressor valves based on the idea that a leaking valve affects the shape of the pressure-volume diagram (pV diagram). This effect can be observed when the valves are closed. To avoid disturbances due to the load control, we concentrate on the expansion phase, and linearize it using the(More)
This paper presents a novel data-driven approach to detecting broken reciprocating compressor valves that is based on the idea that a broken valve will affect the shape of the pressure-volume (pV) diagram. This effect can be observed when the valves are closed. To avoid disturbances due to the load control, we concentrate on the expansion phase, linearized(More)
This paper presents a novel approach to diagnosing faults in reciprocating compressor valves. Based on easily available vibration data, a transformation to a high-dimensional vector space is performed. By defining a metric in this vector space, the distance between the actual compressor state and a reference compressor state is calculated. Excessive(More)
The ambition of NO<sub>x</sub> emission reduction on legacy gas engines for compressor stations leads to focusing not only on improvement of mechanical components but also on enhancing the control. The engine shows a strong coupling and furthermore the compressor clearances are switching fast during transients. Due to the engine inertia the switching is(More)
