Can Your Genset Accelerate to High-speed Running? Come and See!

A customer in Tonghua, Jilin province told us that their gensets couldn’t accelerate to high-speed running. The customer adopts that one HGM9510 control module parallels with two 300KW gensets. The technical staff of SmartGen went to Tonghua to test on site. The result is that the gensets can’t accelerate to high-speed running, “idle speed control” output and warming up delay are normal. After checking GOV, our staff found that warming up delay is only 30s when the acceleration time is biggest. After warming up delay, the acceleration time delay of GOV is still not finished, so the gensets couldn’t accelerate to high-speed running.

Solution
Reduce the acceleration time of GOV and start, the warming up of gensets is normal.

We summary some failure checking and solutions in case other gensets can’t accelerate to high-speed running:
1. Check if the idle control output of control module disconnects after idle timing.
2. Check if the GOV has failure and connections.
3. Check if the“rated speed”of GOV is too low.
4. Check if the acceleration time of GOV is too big.
