Research on the Technical Solution of Multi-Stage Fast Switching Reactor Application on Regional Tie-Line Power Control
Abstract
[Introduction] Control the exchanged power of the regional tie-lines within a reasonable range, which is an important factor to ensure the stability of the power network. However, under some extreme operation modes, the exchanged power of the tie-lines may exceed the limit, especially the large-scale of new energy sources into the power grid, the power of the tie-lines between regions may fluctuate greatly. Therefore, necessary power flow control measures should be taken. [Method] Compared the power flow control methods of several main types of tie-lines and their characteristics, a flexible power flow control method based on multi-stage rapid switching reactor was put forward, and the specific control strategy was studied. [Result] Finally, based on the application of a regional power grid Tie-lines, the function of multi-stage fast switching reactor in controlling the exchange power of regional power grid tie-line was verified. [Conclusion] The results show that the power flow of the tie-line can be controlled flexibly and quickly by using the multi-stage fast switching reactor, and the overall technical economy is better.
