  1. HARMONIC MITIGATION Installation of Mirus harmonic filters in TPS fields Prepared by Ahmed BOUJELBEN Electrical & Instrumentation Engineer Thyna Petroleum Services 7, Avenue Abderahmen EL GHAFIKI BP. 069 - 3069 Sfax Hached SFAX TUNISIA

  2. PIPELINE AND FLOWLINE INTEGRITY • Objectives: • Reduce voltage and current harmonic distortion • Reduce Energy losses • Protect electrical equipment against the harmful effects of harmonics • Avoid failure of equipment ( VFDs, motors, etc.) and especially on • offshore fields (Generator, battery charge, …). • Reduce maintenance cost • Realize energy savings

  3. . As a first step: • TPS selected 4 sites • Mirus was selected as suitable filter technology for all TPS locations • TPS has purchased and installed 4 Lineator filters (2 filters onshore + 2 filters offshore) • Acceptable performances was achieved despite of using filter at light load, Performance will be presented As second step: Mirus solution will be generalized for all TPS fields.

  4. Waveforms Before filter installation After filter installation

  5. Performance measurement (Load rate at 62%)
