2.Functional Features
Multi-function protection:
Provides multiple protection functions such as overcurrent,overload,short circuit,ground fault,overvoltage,undervoltage,overfrequency,and underfrequency.
Advanced protection functions such as sensitive ground fault protection,phase loss protection,instantaneous/intermittent ground fault protection.
High-speed circuit breaker control:
Quickly detect fault signals,and quickly isolate faults by controlling the opening and closing of circuit breakers to protect the safe operation of power equipment and power grids.
Precise measurement:
Using high-precision digital signal processing technology,it can accurately measure signals such as current and voltage to ensure the accuracy and reliability of protection.
It can simultaneously measure and record multiple key electrical parameters,including voltage,current,frequency,power,etc.,and the measurement error is usually no more than±0.2%.
Flexible configuration:
Users can make personalized configurations according to actual needs,including setting protection parameters,time-current curves,etc.
REF615 has twelve standard configurations to choose from to adapt to different feeder protection and measurement and control applications.
Visual operation interface:
Adopting an intuitive operation interface,users can set and query parameters through the LCD display and buttons,which is convenient for operation and maintenance.
Communication and integration:
Supporting multiple communication protocols,such as IEC 61850,Modbus,etc.,it can exchange data and remotely monitor with other intelligent devices.
It can be integrated with the substation management system to achieve efficient communication and monitoring.
III.Application scope
REF615 has a wide range of applications,covering multiple fields such as power generation,transmission,substation and distribution.In the field of power generation,it is mainly used for generator protection and excitation regulation systems in large power plants.In the field of power transmission,it is mainly used for the protection and monitoring of high-voltage transmission lines.In terms of substations,it is widely deployed in substations of various voltage levels as a core protection device.In distribution networks,it is used for feeder protection and automation of urban distribution networks.In addition,REF615 has also found wide applications in the industrial field,such as high-power motor drive systems in metallurgy,chemical industry,papermaking and other industries.
IV.Technical advantages
Highly flexible configuration options:can adapt to a variety of power network environments and grounding methods.
Innovative multi-frequency admittance measurement technology:multi-frequency neutral point admittance measurement using the fundamental frequency and harmonic components in Uo(zero-sequence voltage)and Io(zero-sequence current)can accurately determine the fault direction under complex conditions.
High impedance ground fault(HIZ)detection function:a good combination of protection reliability and sensitivity is achieved through a single function,which can effectively handle low-ohm and high-ohm ground faults,as well as transient and intermittent or heavy-hitting ground faults.
Higher selectivity:able to distinguish different types and degrees of faults to avoid false operation.
Stronger adaptability:suitable for various complex power network environments.
Faster response speed:using advanced algorithms and high-speed processors to achieve millisecond-level fault detection and isolation.
