SPECIFICATIONS

This unit represents basic concepts of the Electric Energy high-voltage three-phase transmission lines operation. It simulates a value modifying concentrated parameter line that allows different configurations and consists on three conductorline (R, S, T) and a Neutral or return line (N).

Each of the phases is represented, following the concentrated parameters theoretical model, through a resistance series association and inductance, along with a parallel association between each one of them in a capacitance effect.

A way to reduce the earth short circuit current is to have impedance in the neutral-to-ground connections. This impedance has no repercussion in the normal functioning of the network but they introduce a repercussion in the increase of 3x Z (impedance on the zero sequence component), o

which reduces the short circuit current.

The return line is simulated through small value impedance that has a resistive-indicative characteristic. To simplify the effect, being a despicable inductance, it will be simulated with a pure 10 resistance.

The phases have two terminals at the input and two at the output, and they are connected at the interior. Through one of them the module will be supplied. Through the last one the natural circuit will continue to the load module, the bar module, the transformer, etc. The two terminals left en every phase is left for assembly of protection relay or other parallel configurations.

The supply of this unit will be done through line terminals (R, S, and T) and the neutral (N) through a 400V three-phase supply and it will be controlled by an interrupter-circuit breaker of 4 poles placed between the supply and the lines module.

In the phases we can distinguish different resistance and inductance values, being able to simulate different length transport lines.

The resistive part is formed by two resistance values of 15 and 33 , with the possibility of making parallel-series connections between them, obtaining two additions resistive values of 10.31 and 48 .

The inductive part consists on a multistage coil of despicable resistance. In which it is possible to choose one of the following values:

33 mH, 78 mH, 140 mH, 193 mH, 236 mH

The capacitive part will be divided into capacitance between conductors and capacitance between line and ground.

The capacitance between conductors is simulated with a pair of capacitors at the beginning and at the end of the line with different values: 0.5 F and 1 F for each conductor.

The capacitance between conductor and ground is 1 F and 2 F, also at the beginning and at the end of the line.

With all this values it is possible to simulate a great number of line configurations, beginning with different line distances with different types of conductor, through the unbalanced lines with different conductors groups (Simplex, Duplex, Triplex and Cuadruplex). At the same time it is possible to simulate transient state with different short-circuits injection using a fault injection module.

The unit is protected with a grounding connection that comes from the metallic caging and that is accessible through a terminal in the front of the module.
