Starting from automation control, expanding into energy, and on to LED, AI and facility planning — covering every field of supervisory control and monitoring for national infrastructure.
HWA KOREA is more than a solar-power company. We started in automation control, expanded into energy, and today we are a total solutions company that also delivers LED and AI systems and facility planning.
HWA KOREA is rooted in automation control. Since 1992 we have manufactured automation control panels and carried out instrumentation works, designing and building supervisory control systems based on PLCs (Programmable Logic Controllers), industrial computers, inverters and converters, and measuring instruments. By centrally and integrally monitoring and controlling field equipment such as motors, pumps and transformers, we deliver stable, efficient operation — the core capability behind all industrial automation.
Supervisory control systems for water and sewage are the core infrastructure for the optimal operation of sewage and water treatment plants. Through automatic analysis and measurement, daily, weekly and monthly data is compiled automatically, and remote monitoring and control is readily implemented on the basis of geographic information systems and information and communication networks. Our water management automation systems also remotely measure and regulate agricultural water from the intake source through main and branch lines, building a stable water supply system.
We centrally monitor and operate switchgear, generator panels and various power facilities within the substation room. Without a separate transducer, PT and CT wiring is used to measure voltage, current, active and reactive power, energy and frequency, with support for peak management and daily report output. The status and abnormal conditions of VCBs and protective relays are collected and analyzed instantly, enabling the prevention of excessive power demand and rapid response.
Tunnel supervisory control systems provide a comfortable, safe environment for drivers and efficient maintenance with cost savings for operators. Various sensors detect and analyze air quality and traffic inside the tunnel in real time and control them to optimal conditions. The road anti-icing system links with road surface detectors and weather observation equipment to automatically spray anti-icing fluid, an eco-friendly, highly stable system that prevents slipping accidents in winter.
The Building Automation System (BAS) is a distributed control system made up of a computer and multiple field control systems. It efficiently operates, monitors and controls facilities within a building — HVAC, lighting, sanitation, security and more — to save energy and improve productivity. Through networking, it connects not only a single building but also remote buildings via a communication network, enabling group management that integrates multiple buildings.
Disaster management systems build an identical information system in duplicate at a remote site, ensuring business continuity even when a natural disaster occurs. Depending on scale, they respond with immediate, several-hour or long-term recovery modes, and years of accumulated weather data analysis make advance preparation possible. The flood warning system automatically detects and alerts to flooding with minimal budget and manpower, minimizing damage.
Our supervisory control systems for solar and wind power generation are integrated solutions spanning modules, structures, junction boxes, inverters, grid-connection panels, weather observation and monitoring. With an open architecture based on Ethernet TCP/IP, generation data is monitored in real time, and faults are addressed quickly even from a remote location. We hold a broad track record, delivering to major power companies and large corporations, local governments and the Public Procurement Service nationwide, as well as exporting overseas.
HWA KOREA is expanding from automation control to energy, and on to LED and AI systems and facility planning and consulting. With AI integrated management systems we digitize production and cost management, and we install LED lighting and electronic displays and plan various facilities. Beyond simple construction, as a consulting partner that designs and plans to meet customer needs, we respond proactively to future changes in the technology environment.
