STATCOM

STATCOM improves grid stability and quality by supplying transmission lines with reactive power.

Hyosung Heavy Industries has the largest capacity for a single substation in the world
using the most recent modular multilevel converter (MMC) technology with high efficiency. We offer STATCOM solutions to domestic and international power companies, renewable energy generation business operators, and industrial facilities.

Features and Benefits

We offer specialized solutions based on superior technology.

  • Scalable

    • MMC technology enables large-capacity control, and STATCOM installation with a single capacity of up to 500Mvar is feasible.

  • Economical

    • Comparative to conventional devices, its compact design reduces land use costs by reducing installation area by 50 to 70%.
    • Realizes low loss through optimal design, and reduces life-cycle costs via routine inspection and maintenance.

  • Green Technology

    • Does not generate harmonics, and offers technology with low noise.
    • All STATCOM facilities are capable of interior design, allowing you to avoid complaints even in densely populated areas.

  • Optimized Solution

    • We analyze the system with the user's system environment, temperature, salinity, humidity, and aseismic conditions in mind, and provide customized and optimized solutions.

  • Long-term Customer Service

    • We ensure product lifespan by providing adequate training for substation users and routine inspections.
    • The easily maintained structure of a converter enables rapid recovery in the event of a failure and ensures a high operating rate.

  • Front Engineering

    • Prior to the specification selection process, we propose diverse and integrated optimal system solutions that meet customer requirements on the basis of a vast array of technology foundations.
