Digital na mga Meter sa Kuryente para sa Malalaking Pampublikong Gusali: Isang Gabay sa mga Sistema ng Pag-iipon ng Enerhiya

I. Background and Objectives

Current Situation Analysis

Mga malalaking publikong gusali, na may kalakihan at mataas na konsumo ng kuryente, naging pangunahing layunin para sa pagmamanage ng kuryente. Ang mga pangunahing isyu ay ang kakulangan ng institusyonal na pagsasanay tungkol sa enerhiya at insufisienteng kaalaman sa pagmamanage, nagresulta sa malaking pagkasayang ng kuryente.

Core Objectives

Itatag ang komprehensibong sistema para sa pag-iipon ng enerhiya at isang direktang sistema ng pagbabantay. Ipaglaban ang sub-item electricity metering sa pamamagitan ng digital power meters upang epektibong tugunan ang isyu ng mataas na konsumo at buong pagpopromote ng implementasyon ng konsepto ng pag-iipon ng enerhiya at pangangalaga sa kapaligiran sa mga gusali.

II. Digital Power Meter Selection Plan

Equipment Comparison Analysis

Selection Recommendation

Inirerekomenda ang intelligent power monitoring meters dahil sa kanilang flexible installation, malakas na system compatibility, at mas magandang suitability para sa sub-item electricity metering needs ng mga malalaking publikong gusali.

III. System Architecture Design

System Components

Ang core components ay kinabibilangan ng microcomputer system, communication devices, at power metering equipment, na nagbibigay ng remote information acquisition, management, monitoring, at coordinated operation kasama ang detection, monitoring, at power systems.

Layered Architecture Model

Isinasaalang-alang ang hierarchical, distributed microcomputer network structure, na nahahati sa sumusunod na tatlong layer:

1. Management Layer
• Tumutugon sa overall system planning and management.
• Gumaganap ng data aggregation, analysis, at decision support.
2. Communication Layer
• Nagbibigay ng information transfer at exchange between layers.
• Sinasiguro ang real-time at reliable data transmission.
3. Field Device Layer
• Inilalagay ang digital power meters para sa front-end data acquisition.
• Nagmomonitor ng real-time operating status ng electrical equipment.

Core Functional Modules

• Parameter Collection: Real-time acquisition of key parameters such as system current, voltage, and power.
• Equipment Status Monitoring: Monitors the operating status of electrical equipment like circuit breakers and switches.
• Electricity Consumption Recording and Statistics: Implements sub-item metering and time-of-use tariff statistics.

IV. Data Acquisition and Processing System

System Platform

Isinasaalang-alang ang data processing platform na itinayo batay sa AcuSys Power Distribution Management System, na may sumusunod na functions:

• Parameter Display: Accurately displays various electrical parameters with real-time refresh.
• Status Monitoring: Presents the communication status of intelligent devices in real-time, promptly identifying device abnormalities and triggering alarms.
• Information Management: Transmits information to the monitoring center via the network for unified management and comprehensive storage.

V. Implementation Case Reference

Project Overview

Case Study: An International Plaza na binubuo ng 28-story main tower at 4-story podium. Ito ay isang comprehensive public building na naglalaman ng opisina, hotel, at commercial spaces, na may kabuuang area na 45,000 square meters at malaking konsumo ng kuryente.

System Configuration

Hardware Configuration:

• Full set of computer protection equipment
• Digital power meters
• ADL system with communication functionality

Network Architecture:

• Communication Management Layer: Communication servers and switches responsible for information exchange, real-time data collection/transmission, and command issuance.
• Field Device Layer: ACR three-phase electricity meters and ADL DIN-rail electricity meters.
• Central Control System: Uses field devices and the communication system as transmission channels to specifically collect circuit information.

Implementation Results

Ang central control room ay maaaring komprehensibong monitorin ang status ng circuit. Ang sistema ay awtomatikong naka-store ng data sa databases at gumagawa ng electricity consumption reports. Ang data ay ipinapakita nang graphical, nagbibigay ng oportunidad para sa timely elimination ng pagkasayang ng kuryente at nagbibigay ng data support para sa susunod na refined management.
