Surge Detection System for Centrifugal Compressor

Problem: The turbo compressor Surge is an unstable operating mode of compression system that occurs at mass flows below the so-called surge line. The instability is characterized by large limit cycle oscillations in compressor flow and pressure rise that reduce compressor performance and endanger safe operation. Approach: The attempt to find a simple model structure which can capture in some appropriate sense the key of the dynamical properties of the physical plant , we study the application possibilities of the anti-surge detection system to protect the turbo compressor from surge by using Neural fuzzy. Results: By simulating new Neural-Fuzzy system which has been made for demonstrate the validity of proposed control scheme, the results shown that the fuzzy system can be a good anti-surge detection system compared by used system. Conclusion: The proposed fuzzy system successfully performed the surge detection like the active detection system of a centrifugal compressor.
