1. Overview
DRL6600U Disturbance Recording and Fault Locating
Device for power system is adapted to substations,
industrial use, railways, and power generation of each
voltage level, where recording the disturbance of power
system is necessary. It truthfully records electric
variables during such events as power oscillation,
frequency collapse or voltage fluctuation, providing
indispensable data support for incident analysis and
operation maintenance.
DRL6600U consist of a recording unit with CPU and
hard disk and a separate HMI. It uses the CPU and
hard disk for recording, and data transfer to the system
data manager or other tasks on the HMI will not
obstruct its main function. Also, the separated HMI can
be used in data analysis without obstructing the
disturbance recording.

Period A: record data before the system disturbance
(PreTrigger)
Period B: record data during the early period of system
disturbance (Trigger)
Period C: record data during the middle and late
periods of system disturbance (PostTrigger)
The disturbance recorder applies the principle of
extendable recording that switches from the A to B and
C periods, ensuring a high resolution during the
PreTrigger and Trigger periods, and adjusting to a
lower sampling rate during the PostTrigger period in
order to reduce the long term storage requirements.
When a new disturbance occurs in period C, the
recording rate switches back to the one of period A,
ensuring that the data recorded both before and after
the disturbance is done at a high rate of sampling.
If one recording happens after another within a short
interval, they are recorded in one waveform file.

5. Current recording
Variation current recording
When the power system is disturbed for some reason
(such as closing a circuit breaker, clearing a
disturbance, or load shedding), the magnitude and
phase of voltage and current may change over time,
which indicates that power system oscillation occurs.
The recorder can be triggered by the variation of
current in a time slot and record these power system
oscillation.
Delta current recording
For some industrial users, the load characteristic is
unstable. During normal operation, the voltage and
current can fluctuate significantly for a long term, under
which circumstance the load characteristic can be
recorded by the recorder for the user to analyze.
Residual overcurrent recording
By using residual current as an operation criterion, it's
possible to show the inrush process of transformer
energization. A large 3I0reflects a three-phase
imbalance in the grid as well, which can be used to
monitor open phase operation on the line.
6. Phase voltage recording
Overvoltage recording
When supplying power over an underground cable or a
network with high capacitance, the phase-to-ground
capacitance of the line may contribute to a voltage rise
(Ferranti effect). Long term operation may pose a threat
to the safety of energized equipment. Thus it's
necessary to monitor the voltage in the power system.
Delta voltage recording
Large-scale electrical equipment and conversion loads
connected to the grid are frequently powered off and
on. A voltage fluctuation will occur when large motors
are started or when large transformer are energized,
during which the recorder can record the voltage
fluctuations for users to analyze.
Third-, fifth-, and seventh-harmonic
overvoltage recording
Severe harmonic pollution effects the normal operation
of electrical equipment, and can damage the power
system. It can lead to capacitor damage due to thermal
overload and insulation breakdown and cause
electrical machine instability. Current and voltage
harmonics in transformers increase copper and iron
losses and in turn causes the temperature to rise,
affecting the insulation and decreasing the overload
capacity margin. Because harmonics also produce
resonance and noise, it's extremely important to record
and analyze harmonics in all segments of the power
system.

7. Rate-of-change frequency
recording
Power system operation has a high requirement for
frequency stability. Subtle frequency changes can
cause huge damage to generators and other electrical
equipment. The DRL6600U can truthfully record
abnormal changes of high frequency, low frequency
and frequency change rate in the power system. It is
widely adopted in power plants, substations, and for
industrial use.
8. Binary signal recording
Crucial binary signal indication information such as
protection operation, reclosing operation and change of
breaker indication can be recorded. Furthermore, the
recorded information reflects the whole process of one
complete disturbance so that crucial operation
information such as false tripping, breaker failure or
reclosing failure can be analyzed.
9. Fault Locating
Fault location by impedance measurement calculates
the linear impedance between the terminal and the fault
location, and in turn determines the distance to the
disturbance.
When the corresponding parameters like line length
and line impedance have been entered, once a phase-
to-ground or phase-to-phase short circuit happens a
recording will be started. Based on the impedance at
the time the short circuit happens, the DRL6600U
automatically calculates and determines the distance
between the device and the fault point.
10. Data analysis
DRL6600U provides a cross-platform waveform
analysis tool, available in both Windows and Linux
operation systems.
With a convenient and fast channel selecting mode, it's
able to show any selected signal on the same page,
and to compare and analyze currents and voltages of
different intervals, and different binary signals.
It can display several modes such as showing
instantaneous, RMS or phasor values. It adopts to
many advanced analysis functions such as sequence
components, power calculation, harmonics calculation,
location and aperiodic component.
With waveform copy and paste functions it's convenient
and fast to select and re-save the required channels of
the record, and then form new waveform files for
accident analysis and fault location.
Direct shortcut keys and tool tips bring users
convenience to operate all software functions.
Through the frequency following mode, accurate
values of analog signals deviating from 50Hz can be
acquired.

11. Operation
Manual recording
Manual recording is available on the HMI.
Remote recording
Remote recording is available via MMS client
Local / remote reset
After disturbance recording, latched LED indicators
and digital outputs can be reset either locally or
remotely.
12. Monitoring
Analog signal sampling monitoring
DRL6600U acquires and stores data from current and
voltage channels with a sampling frequency of 10kHz.
Binary signal monitoring
Binary signal monitoring can display the status of
binary signals.
Disturbance report
Disturbance reports will be formed and saved when a
signal triggers recording or when there are fault
location results
The disturbance report will show automatically after
recording, and can also be manually checked.
The disturbance report will record the start time, subsite
number, subsite name, triggering name, triggering file
name, fault line, fault distance, fault phase, tripping
phase, and current and voltage RMS of one cyclic wave
both before and after the disturbance.
13. Basic IED functions
Self-supervision with internal event list
The self-supervision (INTERRSIG and
SELFSUPEVLST) will respond to internal system
events generated by the different internal self-
supervision functions. Internal events are saved in one
internal event list.
Self-supervision function
The build-in self-supervision function continuously
monitors the hardware and software operation status.
Once a disturbance or abnormality is detected, the
device will send an alarm signal.
Time Synchronization
Clock synchronization makes comparison of events
and disturbance data among all IEDs in the system
possible.
In the IED, the internal time can be synchronized from
the following sources:
•SNTP
•IRIG-B
Authority management ATMNG
All access to device requires authorization. Setting up
users and managing authority levels is realized via the
HMI. There are 3 levels of operation authority: system
management, equipment maintenance and settings
modification.
