Abstract:
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 process variable to test the first process control element, wherein the second process control element is at least one of a device for adjusting guide blades of the turbocompressor, a device for changing the speed of the turbocompressor, and an outlet guide vane for the turbocompressor; actuating the first process control element; and adjusting the second process control element to compensate the process variable, wherein the first process control element and the second process control element control different variables that affect the process variable.
