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.項(xiàng)目概述  Project Overview

　　越南水電站高壓配電室采用SCADA監(jiān)測與PLC控制。客戶通過RS485通訊連接SCADA系統(tǒng)測量，但用4-20mA模擬量信號(hào)控制。安科瑞PZ96-E4/M儀表功能強(qiáng)大，顯示清晰，標(biāo)配modbus-RTU與模擬量，適合客戶現(xiàn)場應(yīng)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.

 

1.PZ系列可編程智能電測儀表介紹  

PZ Series Programmable Intelligent Electric Meters

　　PZ網(wǎng)絡(luò)電力儀表是針對電力系統(tǒng)、工礦企業(yè)、公共設(shè)施、智能大廈的電力監(jiān)控需求而設(shè)計(jì)的。它能測量所有的常用電力參數(shù)，如三相電流、電壓，有功、無功功率，電度、諧波等。由于該電力儀表還具備完善的通信聯(lián)網(wǎng)功能，所以我們稱之為網(wǎng)絡(luò)電力儀表。它非常適合于實(shí)時(shí)電力監(jiān)控系統(tǒng)。

　　The PZ power meter is designed for the power systems, industrial and mining enterprises, public facilities, and smart buildings. It can measure all common power parameters, such as three-phase current, voltage, active and reactive power, electricity, harmonics, etc. Since the power meter also has a complete communication function, we call it network power meter. It is very suitable for real-time power monitoring system.
