South Korea National Assembly Building Project
Release date:
2025-11-24
I. Project Background
South Korea's National Assembly Building is the country's supreme legislative body and a national landmark, serving not only as the heart of the nation's political life but also as a symbol of Korea's national identity and dignity. Inside, it regularly hosts critical activities such as national legislation, budget deliberations, parliamentary oversight of state affairs, and top-level international diplomatic engagements.
To ensure the absolute smooth operation of this national hub, its infrastructure must meet the highest standards. As the existing power system equipment ages and modern, smart buildings increasingly demand unparalleled reliability, safety, and management efficiency in power supply, South Korea’s National Assembly Building has launched a comprehensive upgrade project for its electrical system—designed to guarantee stable operations for decades to come. The project features an exceptionally rigorous selection process, with suppliers chosen globally based on extremely stringent criteria. Jiangxi Yawei Electric, renowned for its cutting-edge technological expertise gained from delivering top-tier solutions in major international projects, as well as its unmatched safety, reliability, and tailored system solutions, successfully won the bid after multiple rounds of intense evaluation. Now, it will provide the core electrical equipment for this iconic national landmark.
II. Customer Needs
This project's demand for power equipment reflects the nation's engineering sector striving for "extreme excellence."
1. Absolute security and political reliability: The system must feature the highest level of security protection, eliminating any risk of meeting disruptions, data breaches, or safety incidents caused by power failures—and ensuring the unwavering continuity and confidentiality of the nation’s core government operations.
2. The highest level of power supply continuity: Core areas such as the main assembly hall, the Library of Congress, data centers, and emergency command centers must achieve "zero-second switchover" for uninterrupted power, with equipment response speeds and control precision required to reach millisecond-level performance.
3. Pure power quality: To ensure the stable operation of electronic voting systems, simultaneous interpretation equipment, security systems, and a wide range of sensitive electronic devices, it is essential to effectively filter out grid harmonics, suppress voltage fluctuations, and deliver a clean power supply comparable to laboratory-grade standards.
4. Intelligent Early Warning and Operations & Maintenance: A comprehensive smart platform is needed—one that integrates real-time monitoring, data analytics, fault prediction, and energy efficiency management. This will enable a transformative shift in maintenance practices, moving from "reactive repairs" to "proactive early warning," ultimately enhancing operational efficiency and effectiveness.
5. Superior craftsmanship and long-lasting durability: The equipment itself must be crafted from premium materials and cutting-edge techniques to guarantee stable performance even under sustained heavy use. Additionally, its designed lifespan should align seamlessly with the building’s overall lifecycle.
3. Product Plan
Jiangxi Yawei Electric has custom-designed a comprehensive, high-end power distribution solution for this project, centered around the core principles of "safety, intelligence, and precision."
1. Fully Redundant Power Supply and Ultra-Fast Switching System: **
* A **Supreme Series Dual Power Automatic Transfer System (ATS)** has been configured for critical loads, featuring magnetic levitation drive technology that delivers switching times significantly faster than international standards, ensuring uninterrupted power supply to essential equipment.
2. **Precision Power Quality Purification System:**
* At critical nodes of the distribution system, **integrated Active Power Filters (APF)** and **Static Var Generators (SVG)** have been deployed to form an active power quality management network, ensuring that the Total Harmonic Distortion (THDi) is tightly controlled below 3%, thereby creating an optimal operating environment for core equipment.
3. **Smart Distribution Management Cloud Platform:**
* We have built the **"iPower-Insight" Intelligent Power Distribution Cloud Management System**, which provides comprehensive coverage across all areas. By deploying thousands of smart sensing terminals, the system achieves millisecond-level collection of building-wide power parameters and enables multi-dimensional analysis in real time.
* The system features advanced capabilities such as **3D digital twin, energy flow topology analysis, early fault diagnosis, and automatic generation of energy efficiency reports**, providing robust data support for operations and maintenance decision-making.
4. **Customized Art-Grade Complete Power Distribution Systems:**
* The switchgear features a **nano-level anti-corrosion coating** and a **modular redundancy design**. Internal connectors are silver-plated, ensuring lower contact resistance and enhanced stability. The overall design not only delivers exceptional electrical performance but also prioritizes both aesthetic appeal and ease of maintenance.
IV. Implementation Results
Since the system was put into operation, Jiangxi Yawei Electric's solution has earned high praise from South Korea's National Assembly for its outstanding performance with "zero failures."
1. **Achieving the Goal of "Absolute Safety" Operation:** Successfully ensured uninterrupted power supply for high-profile political events such as the post-election congressional formation and the annual budget review—activities of the highest political significance—without a single disturbance caused by the distribution system. This fully demonstrates the company’s reliability as a critical national infrastructure provider.
2. **Power Quality Meets Industry Benchmark Standards:** Third-party authoritative testing confirmed that key areas meet or exceed the highest requirements of South Korea’s national standards for power quality, delivering an exceptionally clean and reliable electrical environment tailored to the high-tech equipment housed in the Assembly Hall.
3. **Operations and Maintenance Management Achieves a Digital Leap:** The intelligent cloud platform has freed the operations team from labor-intensive manual inspections, enabling a modern management model of "unattended operation with centralized monitoring." This system delivers fault prediction accuracy exceeding 99%, while boosting operational efficiency by more than 50%.
4. **Outstanding Energy Efficiency, Driving Green Governance:** Through systematic and meticulous energy consumption management, the annual total electricity usage at the Legislative Council Complex decreased by approximately 8% year-on-year, sharply reducing operational costs for public institutions while demonstrating a green, low-carbon governance approach.
5. ** Forging a Golden Brand in the International High-End Market: ** The successful completion of this project serves as a prime example of how Jiangxi Yawei's technological prowess and brand value have earned recognition from leading international clients, firmly establishing the company as an undisputed benchmark in the global high-end government and enterprise markets.
