Key Parameters to Monitor During Gas Generator Set Operation

Paying attention to key parameters during the operation of a gas generator set plays a crucial role in its normal operation and lifespan.

I. Core Engine Parameters

1. Oil Pressure

If low oil pressure is detected, the engine must be stopped immediately; otherwise, problems such as bearing seizure and engine failure may occur.

2. Oil Temperature

Excessively high oil temperature can lead to lubrication failure.

3. Coolant Temperature (Water Temperature)

Excessively high coolant temperature can cause head gasket failure and cylinder scoring.

4. Exhaust Temperature: Excessive heat can lead to poor combustion, knocking, and cylinder head damage.

5. Speed:

1) Unstable speed requires consideration of speed regulation and gas issues.

2) Overspeed poses a serious danger.

II. Gas System Parameters:

1. Gas Intake Pressure:

1) Too low a pressure can cause insufficient load capacity, reverse power, and engine shutdown.

2) Too high a pressure can easily damage components.

2. Gas Leakage Concentration: If an alarm is triggered, the generator must be stopped immediately, gas supply cut off, and ventilation provided.

III. Generator Electrical Parameters:

1. Three-Phase Voltage: Balanced and stable, without significant fluctuations.

2. Three-Phase Current: Balanced three-phase current, without overcurrent or phase imbalance.

3. Frequency (50Hz): Large fluctuations may indicate speed regulation/gas issues.

4. Active Power and Reactive Power: Stable power output, without oscillations.

5. Power Factor: Within normal range, not abnormal.

IV. Parameters to Monitor During Grid-Connected Operation:

1. Reverse Power: If it occurs, it means danger. It must be dealt with immediately

2. Synchronization Status

Synchronization is strictly prohibited.

3. Load Distribution (Multiple Units in Parallel)

The load must be evenly distributed; no single unit should be overloaded.

In addition, attention should be paid to the environment and auxiliary systems, including the machine room temperature, whether the air intake/exhaust is unobstructed, and the operating status of cooling fans and water pumps.
