Reliable detection and safe isolation of faults in electrical powersystems are the objectives of power system protection

§ Line infeed through distributedgeneration in distribution grids

§ Unpredictable renewables§ Volatile and higher utilization of

transmission & distribution capacity –need for resilience

Challenges§ Increased use of directional O/C and

tele-protection in distribution grids§ Enhanced supervision and active

control of power system status, assetsand protection parameters duringoperation

Measures


Innovation is a must for power system protection in orderto meet current and future requirements of the power system’sevolution

SIPROTEC 5 – Adaptive ProtectionRemote control of protection settings through IEC 61850

Problem:Protection settings & thermal limitsare calculated for worst case conditionsà This leads to too restrictive limitsduring >90% of the year

Solution:Adapt settings automatically:à This leads to increased limits during >90% of the yearà This enhances the capacity of the transmissionsystem without building new lines

How is this done:Adapted settings are calculated on control center levelbefore changes of the short circuit currents. The newsettings are then loaded into all protection relays usingIEC61850

SIPROTEC 5 – Arc ProtectionImproved Protection Functionality and personel Safety

Flash over between the poles or to earthed partsSevere risk for personal and equipment

§ Danger for personnel§ Damage of equipment

SIPROTEC 5 relays offer in addition to the base functionsthe possibility of installing optical sensors

§ traditional feeder protection§ detect arc flashes

in order to bypass the time grading of the overcurrentprotection in case of a real arc.High temperatures of ~ 10.000 ºC cause smelting,vaporizing and destruction of the different materials.

The destruction starts after:§ ~ 100 ms: cable sealing ends§ ~ 150 ms: copper§ ~ 200 ms: steel
