ACREL PZ series multi-function meter Application in Vietnam hydropower station

摘要：用户侧用能的透明化、智能化、是当下用能管理的必然趋势。针对用户侧主要的用能节点，设计安装智能仪表，再通过后台系统来实时监控各用能回路的工作状态；并计量各个回路的用电量、用水量、用气量。通过实时监控用能以及相关电力参数、提高用能安全、可靠及维护效率、降低维护的人工成本、实现了配电系统监控的无人值守。通过用能的实时监测，数据的采集及存储，明确供配电系统的运行状态，为用户节约电力维护成本、物业的合理收费提供数据依据。现就越南水电站项目中使用的PZ电力仪表做一简要介绍。

Abstract: The intelligence, refinement and visualization of the distribution system are the trend of distribution management. The smart power meter is designed and installed for the main energy-consuming nodes on the user side, in order to real time monitor the working state of each load circuit by background system,and the electricity consumption, water consumption, and gas consumption of each circuit are measured. Real-time monitoring of energy consumption and related power parameters can improve the safety of energy usage, improve the efficiency of equipment maintenance, reduce labor cost of maintenance, and realize the unattended monitoring of distribution system. Through real-time monitoring of energy, data collection and storage, the operating status of the power supply and distribution system is clarified, it will save electricity maintenance costs and provide reasonable charges for properties. This article shows a brief introduction of the PZ power meters used in the Vietnam hydropower project.

0.项目概述  Project Overview

越南水电站高压配电室采用SCADA监测与PLC控制。客户通过RS485通讯连接SCADA系统测量，但用4-20mA模拟量信号控制。安科瑞PZ96-E4/M仪表功能强大，显示清晰，标配modbus-RTU与模拟量，完好适合客户现场应用。

The high-voltage power distribution room of Vietnam hydroelectric power station adopts SCADA monitoring and PLC control. The customer connects to the SCADA system through RS485 communication for measurement, but uses 4-20mA analog signal control. Acrel PZ96-E4/M meter has various functions, clear display, standard configuration of modbus-RTU and analog output, which is suitable for application.
