产品介绍
RET615 变压器保护测控装置是专用的变压器保护测控装置，用于保护和测控双绕组电力变压器、厂用变压器和升压变压器组，包括电力系统和配电系统中的发电机-变压器组。 RET615 变压器保护测控装置提供八个标准配置，使变压器应用适合不同中性点接地方式的高阻接地或低阻接地相应的接地故障保护方案。所有使用的电力变压器向量组的 CT变比差和相移都得以数字化补偿。RET615 的特征还包括适应变压器高压侧断路器的本地或远程控制。 RET615 变压器保护测控装置以支持变电站 IEC61850 通信标准、并行冗余协议（PRP）和高可用性无缝冗余度协议（HSR）为特点，其中 IEC61850 通信标准包含 IEC 61850-9-2 LE。该装置还支持 DNP3、 IEC 60870-5-103 和 Modbus® 规约。SPA-ZC 302 适配器规约支持 Profitbus DPV1 规约。对于冗余以太网解决方案，RET615 提供带以太网界面的可选通信模块。冗余以太网解决方案建立在基于以太网的 IEC 61850、Modbus® 和 DNP3 规约。RET615 中的 IEC61850 标准涉及纵向通信和水平通信，包括带开关量信号和模拟量信号的 GOOSE 报文，以及基于 IEC 61850-8-1 的参数整定。RED615 同样支持带模拟电压采样值的过程层总线。利用该功能特性，以太网通信可以替代模拟量电信号布线。利用 IEC 61850-9-2LE 规约，测量值作为采样值传递。 RET615 变压器保护测控装置是 ABB 的 Relion® 产品家族中 625 系列的成员。 主要优势 • 一台继电保护装置集成了保护、控制、测量和监视功能 • 为双绕组变压器提供全面的保护和控制功能 • 具有预配置好的的标准配置，亦可通过功能配置快速简便地满足不同的应用需求 • 快速安装和测试的可插拔式设计 • 带可编辑单线图的大液晶显示，可通过本地或基于 Web 浏览器的易于使用的 HMI 来访问 • 周到的产品全生命周期服务
RET615 Transformer protection measurement and control device is a special transformer protection measurement and control device for the protection and control of double-winding power transformers, plant transformers and boost transformers, including generator-transformer groups in power systems and distribution systems. The RET615 transformer protection measurement and control device is available in eight standard configurations to enable the transformer to apply a ground fault protection scheme suitable for high resistance ground or low resistance ground in different neutral ground modes. The CT ratio difference and phase shift of all used power transformer vectors are digitally compensated. The RET615 also features local or remote control of transformer high-voltage circuit breakers. The RET615 transformer protection measurement and control device features support for the substation IEC61850 communication standard, Parallel Redundancy Protocol (PRP), and High Availability Seamless Redundancy Protocol (HSR), where the IEC61850 communication standard includes IEC 61850-9-2 LE. The device also supports DNP3, IEC 60870-5-103, and Modbus® protocols. The SPA-ZC 302 adapter protocol supports the Profitbus DPV1 protocol. For redundant Ethernet solutions, the RET615 offers an optional communication module with an Ethernet interface. Redundant Ethernet solutions are built on Ethernet-based IEC 61850, Modbus® and DNP3 protocols. The IEC61850 standard in RET615 covers both vertical and horizontal communication, including GOOSE messages with switching signals and analog signals, and parameter tuning based on IEC 61850-8-1. RED615 also supports the process layer bus with analog voltage sampling values. Using this feature, Ethernet communication can replace analog electrical signal wiring. Using the IEC 61850-9-2LE protocol, measured values are transmitted as sampling values. The RET615 transformer protection and control device is a member of the 625 series of ABB’s Relion® product family. Key advantages • One relay protection unit integrates protection, control, measurement and monitoring functions • Provides comprehensive protection and control functions for double-winding transformers • Features pre-configured standard configurations, Different application requirements can also be quickly and easily configured with features • pluggable design for quick installation and testing • Large LCD display with editable single-line charts accessible via local or Web browser-based easy-to-use HMI • Thoughtful product lifecycle service
