"Just after finishing a patrol, a fault occurs right away." 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 the sudden deterioration of hidden insulation defects, or sudden factors such as lightning strikes and external damage, or it may be a situation that has not yet appeared during the patrol but develops rapidly in a short time. In the traditional mode, after a power outage due to a fault, operation and maintenance personnel can only "blindly check" based on experience, inspecting every tower along the entire line. This has a wide range, takes a long time, and has a large positioning error, which easily causes a long power outage and directly affects 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: The "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, full-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 give early warnings to 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, it immediately transmits the original signal back to the system master station via a wireless channel. After receiving the data, the master station schedules an intelligent algorithm to perform feature extraction and time-series comparison on the fault waveform. It first delineates the section 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 inspecting every tower along the entire line in the past.

Core Functions

1. Real-time early warning: Monitor recessive faults such as weak line discharge and abnormal fluctuations around the clock, intelligently judge the risk level combined with historical operation data, predict potential faults in advance, realize pre-control, and avoid sudden power outages.

2. High-precision positioning: Accurately lock potential fault points on the line, control the positioning error within ±300 meters, greatly reduce the manual inspection range and improve the inspection efficiency.

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

4. Complete fault recording: Can completely record the power frequency waveform and traveling wave waveform 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 range to a 100-meter section, shortens the repair time, can give early warnings in advance, 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 recordings and diagnosis reports, provides data support for related work, reduces manpower and material resources for inspections, and relies on intelligent algorithms and distributed perception to promote the transformation of power grid operation and maintenance to refined and intelligent, changing the passive operation and maintenance situation.
