On the Power Preservation Strategies of Isolated Grid in Gaobazhou Self-provided Power Station
Gaobazhou Self-provided Power Station is the security station of Gaobazhou Hydropower Station,which under-takes the important task of ensuring the AC power supply.Considering the power preservation conditions of isolated grid in self-provided power station,the power preservation strategies of hydropower units under isolated grid conditions are summarized from the aspects of early preparation,technical measures,and emergency response.In particular,technical measures such as the unit operation strategy,governor operation parameters,and unit protection configuration are adopt-ed for the complex conditions of parallel operation of multiple units,which overcome the common problems such as re-peated pumping of the servomotor,large frequency fluctuations,and improper coordination of multiple units under the i-solated grid condition,and ensure the long-term power supply tasks many times.It can be useful reference for the power preservation of isolated grid in similar self-provided power stations.
