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

摘要：用戶側用能的透明化、智能化、是當下用能管理的必然趨勢。針對用戶側主要的用能節點，設計安裝智能儀表，再通過后臺系統來實時監控各用能回路的工作狀態；并計量各個回路的用電量、用水量、用氣量。通過實時監控用能以及相關電力參數、提高用能安全、可靠及維護效率、降低維護的人工成本、實現了配電系統監控的無人值守。通過用能的實時監測，數據的采集及存儲，明確供配電系統的運行狀態，為用戶節約電力維護成本、物業的合理收費提供數據依據。現就越南水電站項目中使用的PZ電力儀表做一簡要介紹。

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.項目概述  Project Overview

越南水電站高壓配電室采用SCADA監測與PLC控制。客戶通過RS485通訊連接SCADA系統測量，但用4-20mA模擬量信號控制。安科瑞PZ96-E4/M儀表功能強大，顯示清晰，標配modbus-RTU與模擬量，完好適合客戶現場應用。

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網絡電力儀表是針對電力系統、工礦企業、公共設施、智能大廈的電力監控需求而設計的。它能測量所有的常用電力參數，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網功能，所以我們稱之為網絡電力儀表。它非常適合于實時電力監控系統。

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.
