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.

越南(nán)水電站(zhàn)高(gāo)壓配(pèi)電室(shì)采(cǎi)用SCADA監(jiān)測與PLC控製。客戶通(tōng)過RS485通(tōng)訊連接(jiē)SCADA係(xì)統測量，但(dàn)用4-20mA模(mó)擬量信(xìn)號控(kòng)製。安科瑞PZ96-E4/M儀表(biǎo)功能(néng)*，顯示(shì)清晰(xī)，標(biāo)配(pèi)modbus-RTU與(yǔ)模擬(nǐ)量(liáng)，完好(hǎo)適合客戶現場(cháng)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.

PZ Series Programmable Intelligent Electric Meters

   PZ網絡電力(lì)儀(yí)表(biǎo)是針(zhēn)對電力係統(tǒng)，工(gōng)礦企業(yè)，公(gōng)共(gòng)設施，智能大廈的(dí)電力(lì)監控(kòng)需(xū)求而設計的(dí)。它(tā)能測量(liáng)所(suǒ)有的(dí)常用電(diàn)力(lì)參數，如(rú)三相(xiāng)電流(liú)，電壓，有功，無(wú)功(gōng)功(gōng)率，電度，諧波等(děng)。由於該電力儀表還(huán)具(jù)備*的(dí)通信聯(lián)網(wǎng)功能，所(suǒ)以我(wǒ)們稱之為網(wǎng)絡電力(lì)儀表(biǎo)。它非(fēi)常(cháng)適合於實時電力監控(kòng)係統。

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.
