产品介绍：

PSM-E20监控系统主要为合作厂家设计，用于组成各种容量配置的直流系统，可应用于电厂、电站、变电站和各类用户变和其他需要直流供电的场合配合HD系列电力用高频开关整流模块及其他艾默生公司采集模块PSM-E20监控系统可完成智能化电池管理和直流系统监测及告警。PSM-E20监控系统具备远程管理功能，可选择通过 Modbus、CDT91、DNP3.0、EC101或IEC103规约和综合自动化系统通讯上报数据，用于电站实现无人职守。

系统组成
PSM-E20监控系统包括HD系列充电模块内部的监控电路，监控模块(PSM-E20)、配电监控(PFU-12和PFU-13)和绝缘监测仪(JYM-1、JYM-I、JYM-M2和 JYM-S2)，以及电池检测仪(BM-1)等设备，如下图所示。本手册主要介绍监控模块(PSM-E20)和配电监控(PFU-12和PFU-13)的功能特点、安装设计以及调试方法。
PSM-E20监控系统核心模块包括PSM-E20监控块、PFU-12配电监控以及PFU-13 配电监控。下面分别介绍。

PSM-E20 监控模块
1.使用环境
1)工作温度:-5℃~40℃
2)储存温度:-40℃~85℃
3)相对湿度:≤95%(40士2℃)
4)供电电压输入范围:90~300Vdc
2.功能介绍
监控模块是监控系统的数据处理中心。通过COM1~COM4通讯口与PFU-12、PFU-13、HD系列充电模块、JYM-Ⅱ绝缘仪JYM-1绝缘仪、、PBM-1电池仪通讯完成电力操作电源系统运行数据的收集。并根据这些运行数据完成蓄电池组的自动均浮充转换。
如果电源系统有故障产生则弹出告警信息菜单，并点亮告警指示灯，同时控制告警蜂鸣器鸣叫。
监控模块还可将电源系统运行数据通过RS485或RS232通讯接口按用户设定的通讯规约(可选择Modbus、CDT91、DNP3.0、IEC101或IEC103)上报给综合自动化系统，并接收综合自动化系统下发的均浮充控制命令，实现遥控，遥测，遥信功能

PSM-E20

PSM-E20 monitoring system is mainly designed for manufacturers to form DC systems with various capacity configurations. It can be used in power plants, power stations, substations and various types of user transformers and other occasions requiring DC power supply with HD series high-frequency switching rectifier modules and other Emerson acquisition modules PSM-E20 monitoring system to complete intelligent battery management and DC system monitoring and alarm. The PSM-E20 monitoring system has a remote management function and can choose to report data via Modbus, CDT91, DNP3.0, EC101 or IEC103 protocols and the integrated automation system for unmanned power stations.

System composition
The PSM-E20 monitoring system includes the monitoring circuit inside the HD series charging module, the monitoring module (PSM-E20), the power distribution monitoring module (PFU-12 and PFU-13), the insulation monitoring instrument (JYM-1, JYM-I, JYM-M2 and JYM-S2), and the battery detector (BM-1), as shown in the following figure. Intended Audience This document describes the functions, installation design, and commissioning methods of the monitoring module (PSM-E20) and power distribution monitoring module (PFU-12 and PFU-13).
The core modules of the PSM-E20 monitoring system include the PSM-E20 monitoring block, PFU-12 power distribution monitoring, and PFU-13 power distribution monitoring. The following are introduced.

PSM-E20 Monitoring module
1. Use environment
1) Operating temperature :-5℃~40℃
2) Storage temperature :-40℃~85℃
3) Relative humidity :≤95%(40 ℃)
4) Power supply voltage input range :90~300Vdc
2. Function Description
The monitoring module is the data processing center of the monitoring system. Through COM1 to COM4 communication ports, it communicates with PFU-12, PFU-13, HD series charging modules, JYM-II insulation instrument, JYM-1 insulation instrument, and PBM-1 battery instrument to collect the operating data of the power supply system. According to these operating data, the automatic equalization and charging conversion of the battery pack is completed.
If a fault occurs in the power system, the alarm menu is displayed, the alarm indicator is on, and the alarm buzzer is controlled.
The monitoring module can also report the operation data of the power system to the integrated automation system through RS485 or RS232 communication interface according to the user-set communication protocol (Modbus, CDT91, DNP3.0, IEC101 or IEC103 can be selected), and receive the uniform charging control command issued by the integrated automation system to achieve remote control and telemetry.
