项目简介 | Project Introduction
本项目为交直流混合微电网能量路由器成套设备，由稳利达电力电子提供整体直流变换与多端口能量管理解决方案。设备在一台柜内集成三类多端口DCDC功率模块：2台光伏DCDC（MPPT，合计60kW）、2台储能DCDC（并联，合计125kW）、3台负载DCDC（并联，合计89kW，输入输出电气隔离），以270V直流母线（SST固态变压器母线）为核心，实现光伏发电、储能充放电与负载供电之间的灵活能量调度。设备具备10寸本地触摸屏、RS485（Modbus RTU）与以太网（Modbus TCP）双通道通讯，支持遥控、遥测、遥调，保护机制完备，故障解除后自动恢复运行，广泛适用于工业园区微电网、数据中心直流供电、光储充一体化、离网/并网混合供电等场景。
This project is a hybrid AC/DC microgrid energy-router integrated unit, delivered by Wenlida Power Electronics as a complete DC conversion and multi-port energy-management solution. One cabinet integrates three types of multi-port DC-DC power modules: 2 PV DC-DC modules (MPPT, 60kW total), 2 storage DC-DC modules (in parallel, 125kW total), and 3 load DC-DC modules (in parallel, 89kW total, with input-output galvanic isolation). A 270V DC bus (SST solid-state-transformer bus) is the core, enabling flexible energy dispatch among PV generation, storage charge/discharge and load supply. The unit features a 10-inch touch screen, dual-channel RS485 (Modbus RTU) and Ethernet (Modbus TCP) communication for telecontrol, telemetry and tele-adjustment, with comprehensive protections and auto-recovery after fault clearance. It is widely used in industrial-park microgrids, data-center DC power supply, PV-storage-charging integration, and off-grid/grid-tied hybrid supply scenarios.

整套系统配置10寸本地触摸屏，供客户监控数据和触摸操作；提供一路RS485接口，支持遥控、遥测、遥调功能。光伏侧经DCDC 1-2实现MPPT跟踪后接入270V直流母线；储能侧经DCDC 3-4双向变换与电池簇交互；负载侧经DCDC 5-7（输入输出隔离）向直流负载供电；SST固态变压器母线作为交直流能量交换的核心节点。整机功率端口与通讯接口在柜内集成，外部仅需接入光伏、电池、负载与辅助电源。
The system is equipped with a 10-inch local touch screen for on-site data monitoring and touch operation. One RS485 port is provided for remote telecontrol, telemetry and tele-adjustment. The PV side feeds the 270V DC bus through MPPT via DC-DC 1-2; the storage side exchanges with the battery cluster bidirectionally via DC-DC 3-4; the load side supplies DC loads through isolated DC-DC 5-7; the SST solid-state-transformer bus serves as the core node for AC/DC energy exchange. All power ports and communication interfaces are integrated inside the cabinet; only PV, battery, load and auxiliary power need to be connected externally.
