Description

Technical Specifications

Functional Features

Ultra-Fast & Comprehensive Protection

• High-Sensitivity Busbar Differential Protection: Implements advanced ratio and restrained differential algorithms with ≤ 1 ms fault detection, enabling rapid isolation of busbar short-circuit and earth faults without disrupting healthy feeders.
• Multi-Zone Protection: Supports single-bus, double-bus, sectionalized-bus, and 1½-breaker bus configurations with automatic zone selection based on disconnector status.
• Adaptive Backup Protection: Integrates directional overcurrent, earth fault, and distance protection as reliable backup for primary schemes, ensuring layered system security.
• Breaker Failure Protection (BFP): Monitors breaker operation and initiates backup tripping if the primary breaker fails to clear a fault, preventing cascading failures.
• Auto-Reclosing: Provides configurable delayed auto-reclosing for busbar and feeder faults to restore power quickly after transient disturbances.

Advanced Bay Control & Automation

• Auxiliary Power Switching Logic: Executes fast, reliable auxiliary power transfer and backup power auto-switching (BZT) for industrial and power plant auxiliary systems.
• Programmable Logic Control (PLC): Embedded IEC 61131-3 compliant logic engine for custom control sequences, interlocking, and automation tasks without external PLCs.
• Local/Remote Control: Supports manual control via integrated HMI and remote control via SCADA or fieldbus, with secure permission-based access.
• Synchronized Control: Precisely coordinates multi-interval operations (e.g., bus coupling, tie-breaker control) for stable network reconfiguration.

Robust Communication & Integration

• IEC 61850 Compliance: Full support for IEC 61850 MMS, SMV, and GOOSE for seamless interoperability in digital substations, enabling peer-to-peer communication and process bus integration.
• Redundant Ethernet: Dual Ethernet ports with PRP/HSR redundancy eliminate single points of communication failure, ensuring uninterrupted data exchange.
• Multi-Protocol Support: Compatibility with DNP3, Modbus, and IEC 60870-5-103 ensures integration with legacy SCADA and automation systems.
• Time Synchronization: Supports IRIG-B, PTP (IEEE 1588), and SNTP for microsecond-level time alignment, critical for fault analysis and sequence-of-events recording.

Intuitive Operation & Diagnostics

• Integrated HMI: Large, backlit LCD with multilingual support for local status monitoring, parameter viewing, and fault diagnostics.
• Comprehensive Event & Fault Recording: Captures detailed sequence-of-events (SOE) logs, disturbance records, and fault waveforms for post-incident analysis and system optimization.
• Preventive Self-Diagnostics: Continuously monitors hardware health, communication links, and analog/digital inputs, generating pre-fault alerts to enable proactive maintenance.
• Flexible Configuration: Six independent setting groups allow quick adaptation to changing network conditions or maintenance modes via PCM600 software.

Industrial-Grade Reliability

• Wide Environmental Tolerance: Operates stably in extreme temperatures (-25 °C to +70 °C) and high humidity (95% non-condensing), suitable for outdoor and harsh indoor substations.
• EMC Immunity: Complies with strict IEC 61000 standards, resisting electrical noise from switchgear, transformers, and high-voltage equipment.
• Redundant Design: Optional redundant power supply and communication modules enhance availability for critical applications.
• Long Service Life: Industrial-grade components and rigorous testing ensure high MTBF and minimal maintenance requirements.
