Abstract

The periodic testing and validation of grid recovery procedures are mandated by The Indian Electricity Grid Code (IEGC) 20105, which includes Black start procedure for total/partial blackouts and re-synchronization of Island and this procedures needs to practiced at-least twice a year. Black Start mock drills are carried out to learn the behavior of the system while recovering from total/partial blackouts and from such mock drills the engineers will be able to figure out the challenges and responses of the equipment’s at different stages of the procedure. Pench Hydro Power Station is the only Hydro Power Station available nearby and there is no gas generation available in the vicinity of Nagpur district of Maharashtra, India. And Thermal generation available around area is 10000 MW. This paper is the experience about carrying out black start mock drill for 220 kV Khaparkheda Thermal power station from Pench Hydro Power Station and synchronizing of Small Island with national grid created during the mock drill.
