Page 140  EVENTS: Disabled The D30 supports password entry from a local or remote connection. Local access is defined as access to settings or commands via the faceplate. This includes both keypad entry and the RS232 port. Remote access is defined as access to settings or commands via any rear communications port. This includes both Ethernet and RS485 connections.
Page 141 When entering a settings or command password via EnerVista or any serial interface, the user must enter the corresponding connection password. If the connection is to the back of the D30, the remote password must be used. If the connection is to the RS232 port of the faceplate, the local password must be used.

Access to functions depends on user role. The login screen of EnerVista has two options for access to the D30, these being Server and Device authentication.
Page 148 In this case, it uses built-in roles (Administrator, Engineer, Supervisor, Operator, Observer), as login accounts and the associated passwords are stored on the D30 device. In this case, access is not user-attributable. In cases where user-attributable access is required, especially for auditable processes for compliance reasons, use server authentication (RADIUS) only.

Page 159: Clear Relay Records
Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user- programmable pushbuttons to clear specific records is a typical application for these commands. Since the D30 responds to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.

Page 206 CHAPTER 5: SETTINGS File transfer by IEC 61850 The D30 supports file transfer by IEC 61850. The approach is as follows, using the SISCO AX-S4 61850 client software as an example. In the AX-S4 61850 Explorer window, click the Tools menu and access the SISCO File Transfer Utility.
Page 207 NUMBER: 0 The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the D30 over a network. The D30 operates as a TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file obtained from the D30 contains a list and description of all available files, for example event records and oscillography.
Page 208 COMMUNICATIONS  PROTOCOL connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the D30 maintains two sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the D30 at one time.
Page 209 0.0.0.0 The D30 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to which the D30 can connect. A maximum of two simultaneous connections are supported at any given time.
Page 210 PTP, or SNTP, its time is overwritten by these three sources, if any of them is active. If the synchronization timeout occurs and none of IRIG-B, PTP, or SNTP is active, the D30 sets the invalid bit in the time stamp of a time-tagged message.
Page 211 — The configuration field TYP indicates how many measurands are present in the corresponding TYPE IDENTIFICATION (TYP) ASDU. Each ASDU can take either 4 or 9 measurands maximum, depending on the type identification (3 respectively 9). D30 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 5-79...
Page 212 FlexAnalog operands. The measurands sent are voltage, current, power, power factor, and frequency. If any other FlexAnalog is chosen, the D30 sends 0 instead of its value. Note that the power is transmitted in KW, not W. Measurands are transmitted as ASDU 3 or ASDU 9 (type identification value set to measurands I, respectively measurands II).
Page 213 Commands are received as General Command (Type Identification 20). The user can configure the action to perform when an ASDU command comes. A list of available mappings is provided on the D30. This includes 64 virtual inputs (see the following table). The ON and OFF for the same ASDU command can be mapped to different virtual inputs.
Page 214: Modbus User Map
The clock is updated by all sources active in the device. This means that whenever a time synchronization message is received through any of the active protocols, the D30 clock updates. However, given that IEC 60870-5-103, IEC 60870-5- 104, Modbus, and DNP are low-accuracy time synchronization methods, avoid their use for synchronization when better accuracy time protocols, such as IRIG-B, PTP, and SNTP, are active in the system.

The D30 supports the Precision Time Protocol (PTP) specified in IEEE Std 1588 2008 using the Power Profile (PP) specified in IEEE Std C37.238 2011. This enables the relay to synchronize to the international time standard over an Ethernet network that implements PP.

Page 443: Application Of Settings
8.1.1 Overview This chapter provides general application guidelines for stepped distance, overcurrent, and pilot protection. 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.
Page 446 In highly non-homogenous and dynamic systems where the correction for non-homogeneity is not feasible, consider conservative reach (reduced) and/or correction angle (negative) settings. D30 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL...

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.
Page 448: Distance
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.

The memory-polarized mho has an extra directional integrity built-in as shown in the figure.

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.
Page 471 The offset impedance can always be selected successfully to guarantee correct fault direction discrimination regardless of the degree of compensation and location of the series capacitors and the potential source.
