Systems and methods for redundant overvoltage protection functions

A power generation system comprising:

• a rotating machine including a mechanical rotational output configured to output mechanical rotation;
• an electrical generator including a mechanical rotational input connected to the mechanical rotational output, and an electrical output electrically connected to a power distribution system;
• a generator control unit controllably coupled to at least the electrical generator, the generator control unit including a memory and a processor, the generator control unit being configured to operate in conjunction with an overvoltage protection unit including a redundant overvoltage operational test system;
• and
• wherein the redundant overvoltage operational test system comprises an operational amplifier configured to operate as a voltage follower during a first mode of operations, and a point of regulation gain amplifier during a redundant overvoltage operational test.
