GE Multilin 1 Overview 369 revision 3.10 release notes Release details In the following change descriptions, a revision category letter is placed to the left of the description. Refer to the Appendix at the end of this document for additional details. 369 Motor Protection System E Enhanced Motor Learned Data The 369 Motor Learned Data has been enhanced to capture up to 250 sets of motor starting values, averaged over up to five motor starts. These values are available through 369 Setup Actual Values as well as the included 369 Setup Motor Start/Stop Report. The motor learned data is graphically represented through the enhanced Motor Health Report. With the inclusion of the Learned data the information provided with assist with troubleshooting faults that occur during starting, as well as planning preventative maintenance. The following is the learned data captured and stored and can also be printed and filed. • Learned Acceleration Time • Learned Starting Time • Learned Starting Capacity • Learned Running and Cool Time Constant • Learned Stopped Cool Time Constant • Learned Unbalance K Factor • Learned Average Motor Load • Learned Run Time After Start • Date of last learned Date average calculation or last record The Enhanced Motor Learned Data is only available for 369 relays ordered with the Enhanced Diagnostics (-E) option. N Motor Start Data Logger The 369 now provides a high-speed data logger to capture analog signals during motor starting conditions. A total of six individual logs (1 baseline and rolling buffer of last 5 starts), each 30 seconds long are available to record key analog quantities at a sampling rate of 200 milliseconds. The Motor Start Data Logger requires no settings to be entered by the user. The following is captured in the Motor Start Data Logger • • • • • • • True RMS Phase A, B and C Currents Phase Current Unbalance True RMS Ground Current True Phase to Phase or Phase to Ground Voltages Thermal Capacity Accumulated (%) System Frequency Breaker / Contactor Status The Motor Start Data Logger is only available for 369 relays ordered with the Enhanced Diagnostics (-E) option. N 2 Viewpoint Maintenance Settings Security Audit Trail – NERC Compliant GE Multilin Overview 369 revision 3.10 release notes To comply with NERC CIP security reporting requirements and to provide traceability, the 369 maintains a history of the last changes made to the 369 configuration, including modifications to settings and firmware upgrades. A summary history of the last ten sessions is maintained and a list the last 100 specific setting changes are recorded and stored in non-volatile memory. Security Setting Reports include the following information: • • • • Dates and times of security setting changes MAC address of user making setting changes Listing of modified changes How setting changes were made o Keypad, Front serial port, Ethernet The Setting Security Audit Trail is only available for 369 relays ordered with the Enhanced Diagnostics (-E) option. E Enhanced 369 Event Recorder The number of events stored in the 369 Event Recorder has been doubled with the addition of a 16 cycle ocsillography capture. With the increase in the 369 Event Recording and the Oscillography the 369 delivers the capabilities to capture and store all relevant data that is required for analyzing the system after a trip has occurred. This provides efficient and accurate information for troubleshooting persistent problems. Each event is time and date stamped and also includes the nature of the trip. The Enhanced Event Recorder is only available for 369 relays ordered with the Enhanced Diagnostics (-E) option. E DeviceNet: User-Defined Poll Input Data and COS functionality New flexibility and functionality have been added to the 369 in the DeviceNet Poll Data Group. With user defined polling option the user is be able to define the data size and choice of parameters using Modbus User Memory Map. Change of State (COS) functionality is added with this release. Motor and input output status would be available in COS function. This functionality applies for the 369 relays with –D (DeviceNet) interface option. N Enhanced 369 Faceplate The enhanced 369 faceplate contains an improved LCD with 40 readily visible characters. LED indication has-been improved to provide clearer indication of the status of the 369 outputs and protected motor. The enhanced faceplate is included when the Enhanced Diagnostics (–E) option is ordered N Profibus Loss-of-Communication Tripping New settings and functionality have been added to allow the 369 to issue a motor trip in the event of loss of communications with the Profibus Master. Each output relay in the 369 can be configured to operate Failsafe or NonFailsafe after a user-defined delay upon detecting a loss of Profibus communications. This functionality applies for 369 relays ordered with either the –P (Profibus DP) or –P1 (Profibus DPV1) Interface options. N Undervoltage Auto-restart This new element allows the 369 to automatically restart a motor that has tripped due to a loss of AC supply. This is an additional element to the 369, and in no way alters the functionality of the existing 369 Auto-restart element. This element is only available for 369 relays ordered with either the –M or –B option. GE Multilin 3 Overview E 369 revision 3.10 release notes Enhanced Physical Ethernet Connection The Ethernet option (Interface Option –E) has been improved by incorporating an RJ45 Ethernet connector into the 369. This eliminates the need for an external DB9 to RJ45 adapter when using Ethernet communications. N Trip Contact Seal-In The 369 Trip contact can be configured to remain sealed-in by the breaker status to protect the internal relay contacts in the case of a failed breaker. If breaker status seal-in is selected, the trip contact will not open until a change of state is detected by the breaker status input, even if the initial fault condition is cleared. EnerVista™ 369 Setup Software N Motor Settings Auto-configurator The Motor Settings Auto-configurator provides a simplified and streamlined creation of 369 relay setting files by allowing the user to simply input motor nameplate data and general power system data to create recommended settings. By incorporating the Auto-configurator, this eliminates the need cumbersome and lengthy setting file parameters. All motor and system data is entered in six easy steps through the se-up screens. The final settings can be reviewed and overridden by the user to customize the setting file to suit a specific protection philosophy. The Motor Settings Auto-configurator can also produce a summary setting report, in PDF format, outlining settings generated as well as any cautionary notices. N Motor Health Report The Motor Health Report included with 369 Setup provides a detailed history of the operation and performance of the associated motor. By providing critical information as listed in the Enhanced Motor Learned Data and the Motor Start Data Logger, the characteristics of the motor are learned and monitored and provide the key information required for troubleshooting persistent problems and facilitate preventative maintenance. Key motor performance parameters are obtained from the 369 relay, including trip causes, motor learned data parameters and motor start data logs and presented in a PDF report. The Motor Health Report is only available for 369 relays ordered with the Enhanced Diagnostics (-E) option. E Enhanced 369 Event Recorder The enhanced 369 Event Recorder has doubled and is supported in the latest version of EnerVista™ 369 Setup. The Enhanced Event Recorder is only available for 369 relays ordered with the Enhanced Diagnostics (-E) option E Modbus polling time improved for RS485 daisy chain network The Modbus communication is improved to increase the polling speed in daisy chain network. While polling the data from 369 connected in daisy chain, prior to this release there were instances of timeout errors for polling time (dead time) less than 40ms at 19.2 kbps. Now the polling time (dead time) is improved to 2 ms from 40 ms with no timeout errors even at 19200 baud rate.
