Abstract
The invention discloses an electric vehicle charging pile control system and method considering grid frequency safety. The electric vehicle charging pile control system comprises a grid single-phase power input port, a voltage transformer, an AD conversion chip, a first data processor and a second data processor connected successively; the first data processor is further connected with a data real-time display device and a GPS/Beidou signal receiver respectively; the second data processor communicates with an electric vehicle charging pile and an electric vehicle battery pack respectively; and the second data processor is further connected with a man-machine interaction device. The invention has the beneficial effects that: the frequency of a power system can be monitored in real time; when the frequency is relatively low after a fault of the power system, part of unimportant electric vehicle charging loads are cut off to reduce the active power vacancy of the system; low-frequency load reduction is effectively prevented; and the time for restoring the frequency of the power system is shortened.
