Generator set grounding system

In order to ensure personal safety and the needs of power system work, there are strict requirements for 1 mega power generator grounding.

There are three grounding modes: working grounding, protective grounding and protective neutral grounding. The purpose of grounding is as follows:

1. Working grounding

Working grounding is to ground the neutral point, and its purpose is to:

1) Reduce the electric shock voltage. For the system with ungrounded neutral point, when one phase is grounded and the human body touches one of the other two phases, the medium voltage is more than 1.7 times of the phase voltage; For neutral grounding system, the electric shock voltage drops to close to or equal to phase current

2) Quickly cut off the faulty equipment. For the system with ungrounded neutral point, when one phase is grounded, the current path can be formed due to the capacitance and insulation resistance between the conductor and the ground. The grounding current is very small, which is not enough to make the protective device act and cut off the power supply, so as to ensure personal safety. For the neutral grounded system, when one phase is grounded, the grounding current is large, and the protection device will act quickly to disconnect the fault point.

3) Reduce the insulation level of electrical equipment to ground. In a neutral ungrounded system, when one phase is grounded, the ground voltage of the other phase C will rise to the line voltage. For the neutral grounded system, when one phase is grounded, the other two phases are only close to the phase voltage, so the insulation level of electrical equipment and transmission line can be reduced.
