Ensure Long-Term Reliable Operation

Introduction

Reliable operation is essential for every gas power generation project. Regular inspection and preventive maintenance not only improve equipment performance but also help identify potential issues before they affect production.

Recently, EN Energy Technology engineers conducted a scheduled site inspection of the PetroChina Power Station Project commissioned in November 2025. The inspection was part of EN Energy's ongoing after-sales service program, aimed at ensuring the long-term safety, stability, and economic performance of the power station.

PetroChina Power Station Project Commissioning

Comprehensive Inspection to Maintain Optimal Performance

During the inspection, EN Energy's technical team carried out a detailed assessment of the gas generator units and auxiliary systems currently in operation.

The inspection focused on several critical areas:

Engine Operating Parameters

Engine performance data were carefully analyzed, including:

• Engine speed

• Load rate

• Output power

• Exhaust temperature

• Fuel consumption

• Voltage and frequency stability

By comparing current operating data with commissioning records, engineers were able to evaluate equipment performance and identify any deviations that may require preventive action.

Lubricating Oil and Coolant Condition Check

Proper lubrication and cooling are essential for the reliability and longevity of gas generator sets.

The inspection team examined:

• Lubricating oil quality

• Oil pressure levels

• Oil leakage conditions

• Coolant levels

• Cooling system performance

• Potential contamination risks

Maintaining optimal oil and coolant conditions helps reduce component wear, prevent overheating, and extend engine service life.

Intake Air System Inspection

The intake air system directly affects combustion efficiency and generator performance.

Engineers inspected:

• Intake piping integrity

• Air filter conditions

• Pipe connections

• Air leakage risks

• Pressure stability

A properly maintained intake system ensures efficient combustion, lower fuel consumption, and stable power output.

Electrical Wiring and Connection Verification

Electrical reliability is critical for continuous power generation.

The inspection included:

• Wiring integrity checks

• Terminal connection inspections

• Control cabinet assessments

• Sensor connection verification

• Grounding system review

These inspections help prevent unexpected shutdowns caused by loose connections, insulation degradation, or electrical faults.

Proactive Maintenance for Enhanced Operational Safety

At EN Energy Technology, preventive maintenance is considered a core part of project lifecycle management.

Rather than waiting for equipment failures to occur, our engineering team actively identifies potential risks during routine inspections and implements corrective actions before they become operational issues.

This proactive maintenance philosophy helps customers achieve:

• Reduced unplanned downtime

• Lower maintenance costs

• Improved power generation efficiency

• Extended equipment lifespan

• Enhanced operational safety

By moving the safety barrier forward, EN Energy minimizes operational risks and supports the continuous operation of critical energy infrastructure.

Commitment to Long-Term Customer Support

The successful operation of a power station depends not only on high-quality equipment but also on professional technical support throughout the project's lifecycle.

EN Energy Technology provides comprehensive after-sales services, including:

• Routine site inspections

• Remote monitoring support

• Technical troubleshooting

• Spare parts supply

• Preventive maintenance programs

• Operator training

Our experienced service team works closely with customers to ensure every generator system continues to perform at its highest level.
