Confluence field of multi-end flexible direct-current electric transmission system

The invention discloses a confluence field of a multi-end flexible direct-current electric transmission system. The confluence field comprises a confluence field bus, at least three ends of direct-current cable incoming lines are connected with the confluence field bus, a lightning arrester, a current measuring device and an isolation switch are connected between each end of direct-current cable incoming line and the confluence field bus, two ends of direct-current cable incoming lines are connected with the two ends of the confluence field bus respectively, and a single bus wiring mode is adopted as the wiring mode of the confluence field. Because the at least three ends of direct-current cable incoming lines are connected with the confluence field bus in different directions and the lightening arrester, the current measuring device and the isolation switch are arranged between each end of cable and the confluence field bus, energy convergence and distribution for multi-power source power supply and multi-drop point electricity receiving is achieved. Because the single bus wiring mode is adopted, segmented arrangement is not needed, the wiring mode is simple and practical, the economical efficiency is good, and the wiring requirement of the multi-end flexible direct-current electric transmission system is met.
