This paper presents new technical proposal applied to protection coordination
of a real industrial power system.First, the impact of distributed Generators on
coordination of protective devices is discussed.
This technical proposal thus considers both usage of IEC61850 Goose protocol
as well as Directional overcurrent element, because in the future both short-
circuit and earth-fault protection settings of MV feeder Intelligent Electronic
Devices (IED) may need to adapt to changes in network topology resulting
from increased utilization of active distribution network management schemes
(depending on the utilized protection scheme).
Furthermore, real‐time generic object‐oriented substation events (GOOSE)
messages and adaptive protection strategies are used

1. INTRODUCTION (10 PT)
The Industrial Power systems design operates with radial configuration in which power flows from the source
to the connected loads, thus, the coordination of protective devices in the radial system is very simple in nature.
The distribution system contains protection devices, e.g., fuses, reclosers, relays, and circuit breakers. These
protective devices are coordinated in such a way to interrupt the unidirectional flow of the fault current from
the source end towards the fault point
Conventional upstream/downstream protection coordination schemes for radial power system cannot be
applied to microgrids without major modification [2]

2. POWER SYSTEM CONFIGURATION
The industrial plant is an island electrical network without any conection with external grid source
The electricity demand is met by on-site generation, it also compromises four (4) Gas turbine generators 4x 35,
325 MW at 40°C, and provides the necessary electrical power for the normal needs.
In addition to these, an emergency electrical supply system is provided to ensure continuity of operation of
essential and vital equipment following the failure of normal plant electrical supply and for
black start of gas turbines.
This emergency system is based on the concept of four (4) diesel generators supplying a medium voltage (6.6
kV) distribution system feeding the selected emergency loads through medium voltage and low voltage
switchgears located in each substation.
3. POWER SYSTEM MODELLING
ETAP 20.0.1 simulation software, is used for the modeling of Industrial Power System. The electrical system
Modelling was initiated on the basis of the informations gathered from technical characteristics and primary
electrical equipment rating making capacity, transformer technical data sheets, medium and low voltage
motors and circuit breakers data, and protective Devices files relay settings, its graphic representation began
in a single-line diagram. Figure 1 shows only a portion of the single-line diagram extracted from the
simulation software and used for the study case.
The protective devices coordination study is carried out with also the help of specialized ETAP software,
considering the short circuit current values obtained from the short circuit study results, that allow to
determine the fuses breaking current, the circuit breaker trigger points settings and relays settings required, in
order to have properly coordinated protection feeders and incoming circuits, in accordance with the most
widely accepted practices.
4. FALSE TRIPPING OF THE PROTECTION
This phenomenon is known as a sympathetic tripping of the protection, wich occurs in reason of the
contribution of the distribution generation (synchronous generators) to the sustained short-circuit current in
adjacent feeder connected in the same switchgear. [3]
An example is shown in Figure 2,
In order to show its impact to the protective devices coordination, a simulation of a sympathetic tripping is
performed, Figure 3 shows a portion of a typical complex single line diagram, wich is used for the study
case.

Figure 4 shows for three phase fault near in one of the feeders
Although this paper is mainly focusing proposed method could potentially be used for alleviating
sympathetic
5. DIRECTIONAL OVERCURRENT PROTECTION COORDINATION
The coordination of protection devices aims to maintain the selectivity among the devices involved in several
fault possibilities in order to make assure about the safe operation and the reliability of the electric system.[1]

9. CONCLUSION (10 PT)
Provide a statement that what is expected, as stated in the "Introduction" chapter can ultimately result
in "Results and Discussion" chapter, so there is compatibility. Moreover, it can also be added the prospect of
the development of research results and application prospects of further studies into the next (based on result
and discussion).
