"Just finished a patrol, and a fault occurs right after." This is the most genuine frustration of countless transmission operation and maintenance personnel. Transmission lines stretch for dozens or even hundreds of kilometers, crossing mountains, hills, and valleys. A manual line patrol takes several days and consumes huge physical strength. What is even more troublesome is that faults often occur right after the patrol is completed - it may be that hidden insulation defects suddenly deteriorate, or sudden factors such as lightning strikes and external damage, or it may be that the defects that have not yet appeared during the patrol develop rapidly in a short time. In the traditional mode, after a power outage due to a fault, operation and maintenance personnel can only conduct "blind inspection" based on experience, checking each tower along the entire line. The scope is wide, the time consumption is large, and the positioning error is large, which can easily cause a long power outage and directly affect the power supply reliability. TLKS-PMG-DSC Distributed Fault Monitoring Device (AC Type) is the core operation and maintenance equipment developed to end this dilemma.

TLKS-PMG-DSC: "All-weather Diagnosis Expert" for Line Faults

TLKS-PMG-DSC Distributed Fault Monitoring Device (AC Type), with four core advantages of high-precision positioning, all-weather real-time monitoring, whole-process fault tracing, and intelligent analysis and judgment, has become the core preferred equipment for line operation and maintenance in the power industry. This system breaks through the shortcomings of traditional manual operation and maintenance. Relying on distributed perception and intelligent algorithms, it can early warn lines, accurately lock fault points, and automatically retain fault data. It is suitable for operation and maintenance scenarios of transmission lines in complex terrains, greatly improving the efficiency of power grid fault handling and the level of intelligent operation and maintenance, and is widely used in power grid operation and maintenance projects at all levels.

Working Principle

TLKS-PMG-DSC Distributed Fault Monitoring Device (AC Type) deploys monitoring terminals at intervals within the transmission line corridor. Each terminal continuously scans the line operation status. Once abnormal electrical characteristics such as discharge pulses and traveling wave mutations are captured, the original signal is immediately transmitted back to the system master station via a wireless channel. After receiving the data, the master station dispatches intelligent algorithms to perform feature extraction and time-series comparison of fault waveforms. It first delineates the section range where the fault is located, then combines cross-verification of data from multiple terminals to gradually converge to the specific tower section, and simultaneously determines whether the fault is a progressive or sudden event. Finally, the system automatically generates a diagnosis report containing the fault location, type, and waveform, and pushes it to the distribution substation and dispatching center, providing operation and maintenance personnel with precise guidance of "going to repair with coordinates", completely changing the inefficient mode of checking each tower along the entire line as before.

Core Functions

1. Real-time Early Warning: Monitor recessive problems such as weak discharge and abnormal fluctuations of lines around the clock, and intelligently judge the risk level combined with historical operation data to predict potential faults in advance, realizing pre-control and avoiding sudden power outages.

2. High-precision Positioning: Accurately lock potential fault points of lines, controlling the positioning error within ±300 meters, greatly reducing the manual inspection scope and improving inspection efficiency.

3. Intelligent Fault Positioning: When sudden faults such as short circuits and ground faults occur on lines, the system can quickly complete fault analysis and accurate positioning, output fault information in seconds, solving the problem of traditional blind inspection along the entire line.

4. Complete Fault Waveform Recording: Can completely record the power frequency waveforms and traveling wave waveforms at each point of the line at the moment of the fault, retain complete fault data, and provide reliable data support for fault tracing, cause analysis, and operation and maintenance optimization.

Technical Parameters

Application Value

I. From "Blind Inspection of the Entire Line" to "Targeted Repair", improving operation and maintenance efficiency and power supply reliability. TLKS-PMG-DSC Distributed Fault Monitoring Device (AC Type) compresses the fault inspection scope to a 100-meter section, shortens the repair time, can provide early warning, and transforms "post-fault repair" into "pre-fault prevention", reducing the probability of power outages and improving power supply reliability.

II. From "Manual Experience" to "Data-Driven", reducing operation and maintenance costs and promoting intelligent upgrading. The system automatically retains fault waveforms and diagnosis reports, providing data support for related work, reducing manpower and material resources for inspections. Relying on intelligent algorithms and distributed perception, it promotes the transformation of power grid operation and maintenance to refinement and intelligence, changing the passive operation and maintenance situation.
