Power System Protection Co-ordination
|

Protection coordination plans
from Jacobsen elektro includes data for HV
components, control system and relays, system calculations, coordination
analysis and protection settings.
Assisted by a Protection
Documentation tool called ProDoc most aspects of component properties and system conditions are evaluated.
With all information at hand the protection engineer efficiently sets the protection
systems to operate reliably during
faults. This increases the safety for the utility staff and for the public,
and contributes to the optimal operation of the power network |
-
Protecting people and equipment during high-voltage faults
-
Reducing consumer outage time during system disturbances
-
Well coordinated protection gives reliable power system operation
-
We specify, coordinate and install any protection
from any manufacturer
-
Experts in Power System transmission, distribution,
generation and industry

The process
During protection coordination a considerable amount of
information is collected and stored
-
Present and future system configurations.
-
Information of planned expansions.
-
Data on high-voltage component like
lines, transformers, generators, capacitors, motors etc.
-
Short circuit data, earth-fault data and
the result of system calculations and analysis
-
Descriptions of relay software/hardware
including commissioning and maintenance instructions
-
Descriptions and principles of measuring
systems, trip circuits and circuit breakers.
-
Information of the coordination
principles between different relays, fuses etc.
When the data collection is finished the data can be
processed:
-
Extensive power system calculations
-
Relay coordination calculations and
coordination studies
-
Selection of relay settings
-
Documentation of conditions for choices
-
Report errors or deviations and proposed
improvements
Finally the equipment is taken into service:
|

Information is collected processed & evaluated by protection experts |

ProDoc
reduces the workload and enables efficient plan-revision |

Our extensive relay library
includes manuals from all manufacturers |

The final coordination plans are stored on file and in paper archive |
