1. A fluid system for a wind turbine, configured to supply fluid to a lubrication point of one or more consumer units, the fluid system including:
a fluid storage device configured to receive fluid from a pump;
wherein the pump has a normal operation mode in which it operates at a first speed and a low power operation mode at which it runs at a second speed that is lower than the first speed,
a fluid release system configured to operate when the pump is operating in the low power operation mode to release fluid intermittently from the fluid storage device to the lubrication point of the one or more consumer units, wherein fluid is configured to flow from the fluid release system to the lubrication point of the one or more consumer units before flowing back through the pump.
