  • Page 11: Product Description

    2.1.1 Overview The D30 Line Distance Protection System is part of the Universal Relay (UR) series of products. It is a microprocessor-based relay intended for use on transmission lines of any voltage level, without, with, and in the vicinity of series compensation, in three-pole tripping applications.
  • Page 12 PTP (according to IEEE Std. 1588-2008 or IEC 61588), and it allows access to the relay via any standard web browser (D30 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port. The Ethernet port also supports the Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option.

Where relevant, design details and performance characteristics of the D30 are given to facilitate the process of setting the relay for a given application. 8.1.2 Impact of memory polarization The D30 uses a memorized positive sequence voltage as a polarizing signal in order to achieve dependable operation for forward faults and secure non-operation for reverse faults.

  • Page 444: Distance Elements (Stepped Distance Scheme)

    The current supervision alone does not prevent maloperation in such circumstances. Keep in mind that the fuse failure element provided on the D30 needs some time to detect fuse fail conditions. This can create a race between the instantaneous zone 1 and the fuse failure element. Therefore, for maximum security, it is recommended to both set the current supervision above the maximum load current and use the fuse failure function.

  • Page 445: Ground Distance

    To avoid extremely large reach settings, the D30 has the ability to implement any element so that it is reverse looking, which then can provide a back up for the longest line terminated on the local bus. This strategy can be beneficial if the reduced reach helps discrimination between the load and fault conditions, but must be implemented at both ends of the protected line.

    To avoid extremely large reach settings the D30 has the ability to implement any element, so that it is reverse looking. This strategy can be beneficial if the reduced reach enhances the discrimination between the load and fault conditions. When adopted, this approach must be implemented at both ends of the protected line.

    As the characteristics of sub-synchronous oscillations are in complex relations with fault and system parameters, no solid setting recommendations are given with respect to extra security margin for sub-synchronous oscillations. It is strongly recommended to use a power system simulator to verify the reach settings or to use an adaptive D30 feature for dynamic reach control.

  • Page 460: Distance Elements Analysis

    Mutual zero-sequence compensation can raise concerns regarding directional integrity on reverse faults in the situation when the relay gets "overcompensated." This problem does not affect the D30 because its ground distance elements use zero-sequence and negative-sequence currents in extra directional comparators. Both the currents are from the protected line and are not affected by any compensation as the latter applies only to the reach defining comparators: the mho, reactance, and blinder characteristics.

    This extreme steady-state overreach happens during low-current faults when the air-gaps do not flashover or the MOVs do not conduct any significant current. • In addition to the e steady-state overreach effect, sub-synchronous oscillations in both currents and voltages can cause significant transient overreach D30 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 9-17...
  • Page 470 The problem of steady-state overreaching due to the negative reactance of the series capacitors can be addressed in the D30 in a traditional way by shortening the reach of an underreaching distance elements to the net inductive reactance of the line between the potential source and the far end busbar(s). This generic approach has two major drawbacks. First, it leaves large portion of the line uncovered by the directly tripping distance protection.
