摘要：用戶側(cè)用能的透明化、智能化、是當(dāng)下用能管理的必然趨勢(shì)。針對(duì)用戶側(cè)主要的用能節(jié)點(diǎn)，設(shè)計(jì)安裝智能儀表，再通過(guò)后臺(tái)系統(tǒng)來(lái)實(shí)時(shí)監(jiān)控各用能回路的工作狀態(tài)；并計(jì)量各個(gè)回路的用電量、用水量、用氣量。通過(guò)實(shí)時(shí)監(jiān)控用能以及相關(guān)電力參數(shù)、提高用能安全、可靠及維護(hù)效率、降低維護(hù)的人工成本、實(shí)現(xiàn)了配電系統(tǒng)監(jiān)控的無(wú)人值守。通過(guò)用能的實(shí)時(shí)監(jiān)測(cè)，數(shù)據(jù)的采集及存儲(chǔ)，明確供配電系統(tǒng)的運(yùn)行狀態(tài)，為用戶節(jié)約電力維護(hù)成本、物業(yè)的合理收費(fèi)提供數(shù)據(jù)依據(jù)?，F(xiàn)就越南水電站項(xiàng)目中使用的PZ電力儀表做一簡(jiǎn)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(xiàng)目概述 Project Overview
越南水電站高壓配電室采用SCADA監(jiān)測(cè)與PLC控制。客戶通過(guò)RS485通訊連接SCADA系統(tǒng)測(cè)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，完好適合客戶現(xiàn)場(chǎng)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(cè)儀表介紹
PZ Series Programmable Intelligent Electric Meters
PZ網(wǎng)絡(luò)電力儀表是針對(duì)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(cè)量所有的常用電力參數(shù)，如三相電流、電壓，有功、無(wú)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.
