ZADCO Offshore Plant

Problem:

• Unreliable system due to very old generators onsite
• Replacement of the old generators with three (3) new medium voltage generators each
• Needed comprehensive power system study for the generation plant including three new generators alongside the three older generators
• Optimize electrical power management
• Provide load shedding to protect critical operating equipment

Solution: "Comprehensive Power Systems Analysis & Automation"

• Modelign the entire offshor generation plant
• Dynamic modeling of all the existing and new generators inclusing exciters, governors and PSS
• Dynamic modeling of all the large motors / pumps affecting the stability of the system 
• Performed "Power Flow" study and validating all the possible scenarios against the existing benchmarks
• Performed "Short Circuit" study and "Device Evaluation" for worst case scenario faults
• Performed protection evaluation and "Protective Device Coordination" including the medium / low voltage networks
• Performed "Transient Stability" with all the possible scenarios and generators/system impacts to determine the stability limits of the machines
• Set all the under/over frequency and power relays along with the voltage constraint relays
• Equipped the customer with the "Power System Management" and "Intelligent Load Shedding"
