The invention relates to an electric engineering machinery emergency stop control system and method and electric engineering machinery, comprising a power supply management system and a complete machine controller connected with the power supply management system to control the work of the power supply management system, and further comprising an emergency stop control power supply, a positive electrode of the sudden stop control power supply is connected with positive electrode interfaces of the power management system and the complete machine controller through a main circuit of the power-off time-delay relay, and negative electrode interfaces of the power management system and the complete machine controller are connected with a negative electrode of the sudden stop control power supply. The positive electrode of the sudden stop control power supply is further connected with a coil end circuit of a power-off time-delay relay through the first path of the sudden stop change-over switch, and the coil end circuit of the power-off time-delay relay is connected to the negative electrode of the sudden stop control power supply. And the positive electrode of the sudden stop control power supply is connected with the sudden stop signal input port of the complete machine controller through the second path of the sudden stop change-over switch so as to input a sudden stop signal to the complete machine controller, and by adopting the control system, the sudden stop reliability is improved.
