Study on Stereoscopic Power Grid Construction Based on UHV AC Half-Wave-Length Transmission Technology
摘要
Abstract
1Half wave-length AC transmission (HWACT) can be used not only in transmission, but also in power grid construction, utilizing nearly zero connecting impedance characteristics of HWACT line to shorten electric distance between different drop points in receiving gird. In this paper, firstly, the idea of building a stereoscopic power grid based on HWACT was proposed. Then its enhancing effects on changing grid structural form and improving stability of receiving-end synchronous power grid by using point-to-grid HWACT with double (multiple) drop points were studied and analyzed theoretically. Thirdly, simulations based on 2020 planning power grid were carried out to verify feasibility and effectiveness of the proposed idea. Finally, it was concluded that stereoscopic power grid based on HWACT can change form and structure of synchronous receiving grid in large extent, and enhance stability and synchronous power support of synchronous grid.关键词
