Product Introduction

To address the issue of transient surplus power absorption after faults in flexible transmission projects, our company and the CSG Electric Power Research Institute have jointly developed the first energy-self-balanced flexible DC converter valve. It successfully passed on-site testing by an expert group from the CSG Electric Power Research Institute and full-type testing certification by an authoritative third-party organization. This solution addresses the direct threat of excess surplus power to the operational safety of converter stations, which could potentially cause equipment burnout and project shutdowns. This achievement marks another significant breakthrough in the field of flexible DC transmission technology and is of great importance for improving grid operation efficiency and optimizing energy allocation
