Lanzhou Power Supply Company successfully completed the joint commissioning of two sets of SSP-500 safety and stability control devices for 330kV Guanghui substation and Guoneng Guanghui photovoltaic power station.

The safety and stability control system is a control system that can avoid the instability of the power grid in the event of a line failure, thereby preventing large-scale power outages in the system. It is also known as the "second line of defense" of the power grid. With the full cooperation of the staff, the 330 kV Guanghui variable stability control device was successfully put into operation.
