3 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. 2 ABB

Recording mode U/I Trigger Start time of recording 0-25 Cycles A 1-10KHz T-0 Start time of disturbance 0-50 Cycles B 1-10KHz 150 Cycles C kHz Figure 1: A-B-C Recording and IO time sequence 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. ABB 7

9 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 3I0 reflects 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. 8 ABB

10 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 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. 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 phaseto-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. ABB 9

11 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 selfsupervision 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. 10 ABB

12 14. HMI (Human-machine-interface) The LHMI consists of the IED front panel and an HMI. There are status and operation indicators on the IED front panel. DRL6600U-HMI contains the following: an industrial PC, a display (LCD), a keyboard, and a mouse. The HMI is used for setting, monitoring and controlling of DRL6600U. 15. Communication Station level communication The DRL6600U disturbance recorder supports the IEC communication protocol. The device provides 8 Ethernet ports on the DRL6600U-HMI, so that several independent networks can be connected simultaneously. It also provides one Ethernet port on the CPU module of the IED for horizontal GOOSE communication. ABB 11
