Orthogonal Multi-Carrier Modulation(OMCM) is adopted to overcome the frequency selectivity and time variation of low-voltage power line channel.
为克服低压电力线信道的频率选择性和时变性，系统采用正交多载波方式传输信息。

In the voltage correction the voltagevariation of tie-line nodes is considered and is added into the traditional secondary voltage control as the feedback.
在电压校正中，考虑了区域联络线节点的电压变化，并以此作为反馈添加到传统的二级电压控制中。

By means of the proposed algorithm the sensitivity of nodal voltage to any network parameter can be obtained, such as line reactance, variation of reactive power of power grid and so on.
