Objectives

The primary objective of this tender is to procure a comprehensive secondary injection test set, including supply, delivery, and training, specifically tailored for testing protection relays, measurement transducers, and energy meters at Koeberg Nuclear Power Station. The system aims to facilitate accurate, automated, and portable testing of various relay types and associated devices, ensuring compliance with relevant standards and supporting advanced functionalities such as IEC 61850 communication, synchronization, and power quality analysis.

Scope

The scope encompasses the procurement of a multi-phase injection test system with the following features:

• Multiple independent voltage outputs (AC/DC), controllable in amplitude, phase, and frequency.
• Multiple independent current outputs (AC/DC), controllable similarly.
• Low-level analogue signals for relay and transducer testing, including white noise injection for grid compliance.
• Binary inputs and outputs for device control and simulation of plant conditions.
• Analogue inputs for measurement and feedback.
• Auxiliary power supplies for test objects.
• Support for testing various protection relays, synchronizing devices, and measurement transducers.
• Power-system-based simulation software for primary system testing.
• Power quality signal generation and analysis capabilities.
• Advanced software for relay interrogation, GOOSE messaging, sampled values, and IEC 61850 protocol support.
• GPS/IRIG-B time synchronization modules for end-to-end testing.
• Support, calibration, training, and warranty services for five years.
• Compatibility with existing Koeberg testing modules and infrastructure.

Technical Requirements

The technical specifications define the minimum acceptable standards for the system, including:

• Power supply: 230 VAC, 50 Hz, with a maximum consumption of 3450 VA, protected against overcurrent and overvoltage.
• Physical design: Rugged, portable casing with handles, protective feet, and ventilation, suitable for substation environments.
• Connectivity: Ethernet (supporting 10/100/1000 Mbps, PoE), USB, and optional fibre optic interfaces; front and rear panel ports for control and communication.
• Output capabilities: Voltage and current outputs with specified ranges, protection, and indication features; ability to generate both AC and DC signals with high accuracy and low distortion.
• Measurement inputs: Analogue and digital, with high impedance, protected against overvoltage, and capable of recording transient signals.
• Synchronization: GPS and PTP (IEEE 1588) support with specified accuracy and maximum cable lengths.
• Software: User-friendly, Windows-compatible, supporting test automation, report generation, relay setting import/export, and future software updates.
• Standards compliance: IEC 61850, IEC 61000 series, IEC 61400, and relevant international standards for safety, EMC, and performance.
• Support: Local technical support, calibration, repairs, and training services with guaranteed turnaround times.

Summary

The tender aims to acquire a state-of-the-art, portable, and fully integrated multi-phase test system capable of comprehensive relay testing, system simulation, and communication protocol support, ensuring reliable operation within Koeberg's nuclear environment and compliance with international standards.
