ac dc power transmission system 交直流输电系统
The reason was that over the short distances spanned by early power grids, AC transmission suffers lower losses than DC. It thus became the industry standard.
选择交流电作为工业标准的原因很简单，在早期供电距离很短的电网里，交流电的损耗比直流电小。
The Southwest power Pool of Texas is designing an integrated system of DC and AC transmission to enable development of 10 GW of wind power in western Texas.
德州的西南电力联营(Southwest Power Pool)正在设计一个直流交流综合系统使在西德克萨斯州的1千亿瓦的风力发电产物能传输出去。
The result indicates the nonlinear variable structure control can adjust the transmission power of DC line effectively, and assure the stability of the AC-DC system.
仿真结果表明，非线性变结构控制可以有效地调节直流线路的传输功率，保证交直流系统的稳定性。
