Requests for gas units

Static LVRT: Low-Voltage-Ride-Through,

⁄ Requirements define ranges for voltage and which for generating units consist on the
frequency deviations where the generating need to stay connected to the grid during a
units shall not disconnect short-circuit at the point of connection

⁄ Extended power factor range! (POC) following a pre-defined profile
which is different in each country.

Dynamic

⁄ Not to disconnect from network in Certification: Country specific - eg. BDEW
the event of LVRT network faults
⁄ Support with reactive current • Unit certification (Einheitszertifikat)

⁄ After fault clearance not to extract more inductive – from supplier
reactive power than prior to fault
• Plant certification (Anlagenzertifikat)
– customer for plants > 1MVA
