Sl. No. Parameters Requirements Reference Overall Conditions of Service Reference to regulations Conditions for Supply of Electricity of Distribution Licensees in the State of Karnataka Overall Grid Standards Reference to regulations Central Electricity Authority (Grid Standards) Regulations 2010 Equipment Applicable industry standards IEC/EN standards Safety and Supply Reference to regulations, Chapter III (General Safety Requirements) Central Electricity Authority (Measures of Safety and Electricity Supply) Regulations, 2010 and subsequent amendments Meters Reference to regulations and additional conditions issued by the Commission. Central Electricity Authority (Installation & Operation of Meters) regulations 2006 and subsequent amendments Harmonic Current Harmonic current injections from a generating station shall not exceed the limits specified in IEEE 519 IEEE 519 relevant CEA (Technical Standards for Connectivity of the distributed generation resource) regulations 2013 and subsequent amendments Synchronization Photovoltaic system must be equipped with a grid frequency synchronization device, if the system is using synchronizer inherently built into the inverter then no separate synchronizer is required. Relevant CEA (Technical Standards for Connectivity of the distributed generation resources) regulations 2013 and subsequent amendments. 8. Voltage The voltage-operating window should minimize nuisance tripping and should be under operating range of 80% to 110% of the nominal connected voltage. beyond a clearing time of 2 seconds, the Photovoltaic system must isolate itself from the grid.
Technical Standards for Interconnection Flicker Operation of Photovoltaic system shouldn’t cause voltage flicker in excess of the limits stated in IEC 61000 or other equivalent Indian standards, if any Relevant CEA regulations 2013 and subsequent if any, (Technical Standards for Connectivity of the distributed generation resource) Frequency When the Distribution system frequency deviates outside the specified conditions (50.5 Hz on side and 47.5 Hz on lower side up to 0.2 sec), the Photovoltaic system shouldn’t energize the grid and should shift to island mode DC Injection Photovoltaic system should not inject DC power more than 0.5% of full rated output at the interconnection point. or 1% of rated inverter output current into distribution system under any operating conditions Power Factor While the output of the inverter is greater than 50%, a lagging power factor of greater than 0.9 shall be maintained Islanding and Disconnection The Photovoltaic system in the event of voltage or frequency variations must island/ disconnect itself within IEC standard on stipulated period Overload and Overheat The inverter should have the facility to automatically switch off in case of overload or overheating and should restart when normal conditions are restored
