Abstract
Official abstract text for this publication.
A turbomachine has a first process control element, a second process control element, and a test system for testing the first process control element. The first process control element and the second process control element influence the same process variable. To test the first process control element, the test system changes the process variable by means of the second process control element. This change in the process variable caused by the second process control element is compensated again by means of the first process control element.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for testing the functionality of a process control element of a turbomachine, the turbomachine comprising a first process control element configured as a surge valve to control a process variable, a second process control element configured as a guide blade actuating drive to control the process variable, and a test system for testing the first process control element, the method comprising: actuating the second process control element to change the…
