描述
主要产品详情及功能
馈线保护与控制：其主要作用是为配电网中的架空线路和电缆馈线提供全面的保护、控制、测量和监测。这包括放射状、环状和网状配电网，甚至包括分布式发电网络。
全面的保护功能：REF615提供广泛的保护功能，包括但不限于：
方向性和非方向性过流保护：用于检测和隔离由过电流引起的故障。
接地故障保护：用于检测接地故障，这在不同的接地系统（非接地、电阻接地、补偿接地、直接接地）中尤其具有挑战性。这包括高灵敏度和选择性选项。
热过载保护：防止设备因过热而损坏。
电压保护：包括过压、欠压、零序过压和序分量电压保护。
频率保护：过频、欠频和频率变化率保护。
断相保护：用于检测断线。
断路器失灵保护：即使主断路器失灵，也能确保故障被清除。
可选电弧故障检测：通过硬件和软件增强，它可配备三通道电弧故障检测系统，用于监控开关设备。
集成控制功能：除了保护功能外，它还集成了基本的控制功能，允许通过前面板人机界面(HMI)或远程控制系统对单个断路器进行本地或远程控制。
测量和监控：它提供广泛的电流、电压、频率、功率和电能质量测量功能。它还包括故障定位、扰动记录和事件记录等功能，可用于故障后分析和系统维护。
先进的通信功能（符合IEC 61850标准）：615系列的一大优势在于其完全符合IEC 61850第1版和第2版标准。这使其能够：
GOOSE（通用面向对象变电站事件）消息传递：用于IED之间的高速点对点通信，这对于保护方案至关重要。
HSR（高可用性无缝冗余）和PRP（并行冗余协议）：用于变电站内高度冗余且具有弹性的通信网络，即使单个网络发生故障也能确保数据流不间断。
IEC 61850-9-2 LE（精简版）：支持过程总线应用，允许通过非常规互感器进行数字通信，从而减少布线。
支持其他协议：也兼容IEC 60870-5-103、Modbus®和DNP3。
Key Product Details and Functions
Feeder Protection and Control:Its primary role is to provide comprehensive protection,control,measurement,and supervision for overhead lines and cable feeders in power distribution networks.This includes radial,looped,and meshed distribution networks,even those with distributed power generation.
Comprehensive Protection Functions:The REF615 offers an extensive range of protection functions,including but not limited to:
Directional and Non-Directional Overcurrent Protection:To detect and isolate faults caused by excessive current.
Earth-Fault Protection:For detecting ground faults,which can be particularly challenging in different earthing systems(ungrounded,resistance-earthed,compensated,solidly earthed).This can include high-sensitivity and selectivity options.
Thermal Overload Protection:To prevent damage to equipment from overheating.
Voltage Protection:Including overvoltage,undervoltage,residual overvoltage,and sequence component voltage protection.
Frequency Protection:Overfrequency,underfrequency,and frequency rate-of-change.
Phase Discontinuity Protection:To detect broken conductors.
Breaker Failure Protection:To ensure faults are cleared even if the primary circuit breaker fails.
Optional Arc-Fault Detection:Enhanced with hardware and software,it can feature a three-channel arc-fault detection system for supervision of switchgear.
Integrated Control Functionality:Beyond protection,it integrates basic control functions,allowing for local or remote control of one circuit breaker via its front panel HMI or a remote control system.
Measurement and Monitoring:It provides extensive measurement capabilities for current,voltage,frequency,power,and power quality.It also includes functions like fault location,disturbance recording,and event logging for post-fault analysis and system maintenance.
Advanced Communication Capabilities(IEC 61850 Compliant):A key strength of the 615 series is its full compliance with IEC 61850 Editions 1 and 2.This enables:
GOOSE(Generic Object Oriented Substation Event)messaging:For high-speed peer-to-peer communication between IEDs,crucial for protection schemes.
HSR(High-availability Seamless Redundancy)and PRP(Parallel Redundancy Protocol):For highly redundant and resilient communication networks within substations,ensuring uninterrupted data flow even with single network failures.
IEC 61850-9-2 LE(Light Edition):Support for process bus applications,allowing for digital communication from non-conventional instrument transformers,reducing wiring.
Support for other protocols:Also compatible with IEC 60870-5-103,Modbus®,and DNP3.
