Abstract: The stability control device adopts advanced platform based design concepts and provides standard model services for applications through hardware and software modular design. The stability control device is a control device installed in power plants or substations to ensure the stability of the power system when encountering large disturbances in the land power grid. It achieves functions such as machine cutting， load cutting， and rapid output reduction according to standardized strategies. This article studies the standard services of domestic power grid stability control devices， develops stability control strategies suitable for offshore platform power station management， completes the intelligent strategy and functional research and development of stability control devices， configures stability control master and slave machines according to on-site strategy requirements， and develops control and disposal strategies and intelligent requirements suitable for on-site working conditions.

Key words: strategy, stability control host, stability control slave, instantaneous value
