چکیده
In this article are presented the basic principles of the numerical protections used for protecting the high-voltage electric lines (110 kV). Is achieved a study for implementing a numerical distance protection DIPA 100, for a high-voltage line (an example from practice). For the numerical relay, is shown the protection characteristic of DIPA 100, characteristics of operation to faults ‘phase-phase’ and characteristics of operation to faults ‘phase-ground’. By using of numerical protections for the high-voltage electric lines, is ensured an easy implementation in practice and a protection qualitatively superior compared with the classic protections.

In this paper, an interval approach is presented to achieve perfect selectivity and maximum sensitivity in distance relay zones, considering uncertainties. For this purpose, first, the uncertainties affecting the settings of the three zones of a distance relay are discussed. Then, by using the Monte-Carlo simulation, the uncertainties are modelled and the impedances seen by the distance relay a...

متن کاملConsidering Pilot Protection in the Optimal Coordination of Distance and Directional Overcurrent Relays
The aim of the relay coordination is that protection systems detect and isolate the faulted part as fast and selective as possible. On the other hand, in order to reduce the fault clearing time, distance protection relays are usually equipped with pilot protection schemes. Such schemes can be considered in the distance and directional overcurrent relays (D&DOCRs) coordination to achieve faster ...
متن کاملDetection of power oscillation and simultaneous faults using Clark transform
Distance relays are widely used to protect transmission lines. Sometimes, in these lines due to the occurrence of the oscillation of the power, the impedance calculated in the distance relay enters into its functional zones and leads to the cutting off of the lines. This issue can cause global power outages. Accordingly, in this paper, a Clark-based method for detecting the oscillation of power...
