Online GIS PD monitoring system sumala sa IEC61850 protocol

Pagtukod sa Partial Discharge (PD) sa GIS

Ang mga paraan sa UHF (Ultra-High Frequency) ug ultrasonic mahimong maayo sa pagtukod sa partial discharges (PD) sa Gas-Insulated Switchgear (GIS), bawgad nimo ang ilang kaugalingong mga abilidad:

• UHF Method: Natukod ang PD pulses pinaagi sa high-frequency electromagnetic waves gipasabot sa PD activity sa loob sa GIS.

• Ultrasonic Method: Nakakaila sa ultrasonic waves gipasabot sa bubble shocks gipasabot sa PD.

Key Monitoring Data

Ang pangunahon nga data nga gitukod sa GIS PD monitoring system mao kini:

• UHF PD signals

• Ultrasonic PD signals

• Transformer voltage signals

Ang online monitoring system mogamit kini nga mga signal ug mogenera og alarm information batas sa operational status sa GIS.

System Composition

Ang GIS PD monitoring system gisulay sa tulo ka core components:

• Sensors: Nakuha ang PD-related signals.

• UHF PD sensors natukod electromagnetic signals.

• Ultrasonic sensors sukad acoustic signals.

• Data Preprocessing System: Conditions ug prepares signals para sa analysis.

• PD Monitoring IED (Intelligent Electronic Device): Processes, stores, ug displays data sa bay level.

Signal Flow ug Communication

• Process Level: UHF ug ultrasonic sensors nakuha electrical ug acoustic signals, nga conditioned ug transmitted sa PD monitoring IED.

• Bay Level: Ang IED stores, displays, ug processes data. Specific communication service mapping (per IEC 61850) defines network transmission standards for sampled values between the process and bay levels.

• Station Level: Data is reported from the bay level to the station level via predefined communication services for centralized monitoring.
