Abstract

The hydrogen plant control system experienced six trips within a two-month period. This resulted in the cessation of hydrogen gas (H2) production and posed several potential risks to the generator, including: first, the potential overheating of the generator rotor, which could reduce the isolator’s lifetime. Second, it could potentially lead to a unit trip due to a cooling failure in the generator rotor. Based on the analysis of the above issues, it was found that the control wiring for H2-A and H2-B was merged into a single 220-V phase voltage source. In the event of a short-circuit fault, this simultaneously caused hydrogen generators A and B to stop production. To address these trip faults in the hydrogen generator, wiring modifications were made to the Process Control Cabinet (PCC) panel by drawing power control cables of 220 V for each hydrogen generator (Parallel Power). This modification included the installation of fuses and indicator lights. As a result, the 220-V power source was divided into two: first, power control for hydrogen A, and second, power control for hydrogen B. After the wiring modifications were implemented, it prevented simultaneous trip failures in hydrogen generators A and B. To date, if a short-circuit occurs in one of the hydrogen generators, the other hydrogen control system can still operate and produce H2 gas. Additionally, this modification was made to assist the operations team in notifying the maintenance team of any abnormal H2 system conditions.
