Control method of parallel type hybrid power excavator power system
The invention provides a control method of a parallel type hybrid power excavator power system. The control method includes the following steps that A, the vibration amplitude a of a shaft system is inspected, the step B is executed if the vibration amplitude a of the shaft system is smaller than a set value a[1], and otherwise the step H is executed; B, time delay judgment is conducted, if time delay t is smaller than set time delay t[1], the step C is executed, and otherwise the step J is executed; C, the charge state s of an energy storage device is inspected, if the charge state s is larger than a set value s[1], the step D is executed, and otherwise the step K is executed; D, output pressure p of a hydraulic pump is inspected, if the output pressure p is larger than a set value p[1], the step E is executed, and otherwise the step K is executed; E, an ISG motor is kept working at the electric state; H, the ISG motor is kept working in the idle state, and a time delay program is started; J, an engine is stopped through a controlled, and an alarm signal is given out; and K, the ISG motor is kept working at the electricity generation state. By means of the method, the working safety of the power system can be effectively improved.
