Control system of AC diesel generator set adopted the AC module of ROSSHILL 1400 or adopted numerical control system. It can be applied to CAT3512A、3512B or other diesel generator.

The active voltage adjustment rate of AC control components is less than 1%, the reactive voltage adjustment rate is 3%, and the frequency stability rate is less than 1%. All AC components can be replaced with each other and can be quickly repaired; the components have over-frequency protection, under-voltage protection, over-voltage protection, reverse power protection and pulse loss protection. The component parts have passed the aging test, which is stable and reliable, and the failure rate is low. It can be applied to generator set control in land drilling and offshore platform .
