Zhuhai Gopower Smard Grid Ltd. Formerly known as Zhuhai GoPower Electronics Co Ltd. The company was founded in 1998. She was one of the very beginning high-tech companies, which engaged in research and study intelligent controlling of medium voltage (12KV-40.5KV) transmission and distribution equipment. She was one of the members of smart grid coalition. After 21 years of painstaking exploration and development, she has grown into the intelligent transmission and distribution leader in the field. She involved in the construction of the intelligent control of transmission and distribution Automatin project, which was remarkable construction of Beijing Olympic Games. Products according to international standard IEC61970 IEC61968 IEC61850. The design met the part V of IEC60870, including 101 equilibrium of the statute, 101 non-equilibrium of the statute, 104 statute and DNP3.0 statute. Our company participated in the national standard of '12KV insulated ring main unit solid and '12KV high voltage AC automatic cut-off switch'. The controller could match with switch achieving single nearest control, to finish fault handling within boundary. This method will not affect power supplying of non-fault user. Using backstage management system software of BW-2009-4G and BW-2008-3G, through a variety of communication skills, realize distribution network real-time control and monitor. Achieve a fully integrated management and optimization, to improve distribution network supply reliability. We will focus on the overall solution of smart distribution network. Contribute to national smart grid construction.
