Testing and Commissioning - Generators

Job Requirements

Location: Japan

Work Scope: You will be responsible for testing and commissioning electrical equipment related to generator control and protection systems at thermal power plant sites.

Experience: 4 to 10 years

Equipment Includes:

• Generator Exciters
• Static Frequency Converters (SFC)
• Generator Control Panels
• Protection Relays for Generator/Transformer
• Auto Synchronizers

Key Responsibilities:

• Perform testing of generator-related panels and circuits at site
• Conduct interface checks between panels
• Commission generators and associated systems
• Execute site tests before and after GT (Gas Turbine) start-up

Typical Site Activities:

• Before GT Start:
• Power receiving
• Panel testing within scope
• Loop checks with external panels
• Interlock and phase relation tests
• After GT Start:
• No-load and on-load tests (50%, 75%, 100%)
• Load rejection tests
• Performance tests
• Special tests required by grid operators (e.g., NERC compliance)

Work Experience

• Required Skills & Experience:
• Technical Experience:
• Minimum 4 years in testing and commissioning electrical systems for thermal power plants.
• Hands-on experience with generator control systems, excitation systems, and protection relays
• Strong understanding of generator main circuit, synchronization, and interlock logic
• Experience in site testing procedures, including:
• Power receiving and energization
• Loop checks and interface verification
• Interlock and phase relation tests
• Load rejection and performance tests
• Familiarity with grid compliance standards (e.g., NERC, IEEE)
• Preferred Experience:
• Commissioning of combined cycle power plants
• Knowledge of Static Frequency Converter (SFC) operation and troubleshooting
• Experience with SCADA/DCS systems integration
• Ability to interpret electrical schematics, wiring diagrams, and logic drawings
• Previous overseas commissioning experience
