List and state any four limitations of inter connected power station.
by

1 Answer

Answer :

Limitations of inter connected power station:-

1) Initial cost of infrastructure of transmission line increases as length increases. 2) Interconnection required more automation which increases cost on various control equipments and load center. 3) Control and maintain magnitude of voltage and frequency within permissible limit of various generating station is difficult task. 4) Control of reactive power is the major issue. 5) Losses in transmission line increases as length of transmission line are more. 6) There is possibility of cascade tripping and overall black out in large interconnected system. 7) Interconnection is possible only when magnitude of transmission voltage and frequency is same. 8) Interconnection assumes that some areas have surplus generating capacity. But in absence of surplus power merits of interconnection cannot be obtain.
