DRSN1 / DRSN100 – Power Swing Protection
Products family : Voltage Protection
Sector : Transmission
Some lines 400 kV and 225 kV transmission network interconnect the power plant generators allowing them to remain synchronous: they are a synchronizing link.
Worldwide, some major incidents have resulted in production losses of synchronism groups then GENERATE voltage beats on interconnection links; they could have significant consequences in terms of customers or cut geographical areas blackout.
To secure these connections, thereby limiting the effects of a loss of synchronism, protection of unwinding rupture DNSR synchronization enables:
– Detection of voltage beats accompanying loss of synchronism
– Automatic unwinding a troubled interconnector
It is interchangeable with the previous generation of ICE relay (TDRS51B / DRS50)
