Description

technical field

[0001] The invention relates to a system in the field of power system power flow control, in particular to a distributed synchronous series compensator. Background technique

[0002] Flexible AC transmission system (Flexible AC transmission system, FACTS) usually needs to install various compensation devices, such as thyristor-controlled series capacitor (TCSC), static Synchronous compensator (STATCOM), static synchronous series compensator (SSSC), unified power flow controller (UPFC), etc. These FACTS devices are either connected in series in the transmission line or connected in parallel on the busbar, and achieve the purpose of controlling the power flow of the line by changing the impedance of the series-connected line or the voltage of the busbar.

[0003] The above-mentioned traditional type FACTS compensation devices have a common feature, that is, centralized compensation. A point on the line is selected to install compensation equipment. This type o...
