At the last Technology Evening, Ludy Groenewoud from CCC in the Netherlands presented an introduction to turbo-machinery control, emphasising the negative effect of poor compressor control. He explained the term ‘surge’ and its consequences, stressing the need for anti-surge control taking into consideration that flow reverses in 20-50 ms. He showed the audience photos of turbines that were damaged by overspeed to demonstrate the need to ensure that correct machine protection is implemented. The API/ISO governance and protection speed requirements were also explained.
