0. Introduction

As electricity networks continue to expand and power consumption increases, the need for advanced power management solutions has become more critical than ever. Users are now more aware of energy efficiency and demand more reliable, accurate, and cost-effective systems to manage their electrical infrastructure. In response, the Acrel-3000 power management system offers an integrated solution that combines intelligent monitoring devices with modern communication technologies to provide real-time insights into power usage and system performance.

1. Project Overview and Objectives

Located in the northeastern part of Yunnan Province, the North New District Hospital of Zhaotong City serves as a key healthcare facility in the region. Positioned at the intersection of Weixin Road and Caiyun Road within Zhaoyang Industrial Park, the hospital is designed to provide comprehensive medical services, including general surgery, orthopedics, internal medicine, emergency care, gynecology, and more. It also features five specialized centers such as the dialysis center, physical therapy rehabilitation center, and radiology imaging center. Notably, the geriatrics department integrates medical and health care services, offering a range of support for elderly patients.

This project involves the deployment of Ankerui smart power meters at the hospital to collect real-time data on electrical parameters such as voltage, current, and power. The collected data is processed and displayed on a primary map, allowing for real-time monitoring of each circuit's status. Customized energy reports are generated to help analyze power consumption patterns and improve overall efficiency.

2. Design of the Power Management System

The design of the power management system takes into account the specific needs of the hospital, including the structure of the power network, load capacity, and operational requirements. By selecting appropriate monitoring equipment, the system ensures efficient operation, reduces costs, and enhances functionality. The system supports real-time monitoring of power distribution circuits, providing detailed information on power status, alarms for overloads, and network communication capabilities. It also facilitates the generation of reports and visualizations to aid in maintenance and decision-making.

2.1 System Architecture

The system follows a hierarchical distributed architecture, consisting of three main layers: the station management layer, the network communication layer, and the field device layer. The station management layer handles data processing, visualization, and user interaction through software and hardware components like industrial computers, printers, and UPS systems. The communication layer uses serial servers to facilitate data exchange between field devices and the central system. The field device layer includes instruments such as the ARC72 and DTSD1352 series, which monitor electrical parameters and circuit breaker statuses.

2.2 Network Design

The network system allows for real-time data transmission and quick execution of commands, forming the foundation for the system’s functionality. Devices on-site are connected via a field bus, and all buses are linked to a communication collector for seamless data transfer to the host system.

2.3 Software Function Design

The software is designed to meet the hospital’s specific needs, offering functions such as main wiring diagram display, remote measurement, alarm for parameter limits, event recording, fault detection, report generation, and user rights management. These features ensure effective power monitoring and system control.

2.3.1 Data Acquisition and Processing

Data acquisition involves both analog and digital inputs, capturing voltage, current, power, and other key parameters. Switching signals are also monitored for circuit breaker status and faults. Collected data is displayed in real time and stored in a database for future reference.

2.3.2 Data Reporting and Statistics

The system provides detailed energy reports, enabling users to track power consumption across different circuits. This helps identify anomalies, ensure accuracy, and support informed decisions.

2.3.3 Current Curve Analysis

The system generates load trend curves for incoming and critical circuits, helping maintenance teams monitor power demand and system load distribution. It also records fault data for analysis and troubleshooting.

2.3.4 User Rights Management

The system includes user access controls to prevent unauthorized changes and ensure secure operation. Different levels of access can be assigned based on user roles.

3. Significance of the Energy Management System

The implementation of the Acrel-3000 system at the North New District Hospital demonstrates how advanced power management can enhance operational efficiency and reliability. By enabling real-time monitoring, fault detection, and data-driven decision-making, the system contributes to safer and more sustainable power distribution. It not only improves the hospital’s energy management but also delivers economic benefits through reduced waste and improved resource utilization.
