Embodiment Construction
[0032] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0033] A method for suppressing chaotic oscillation of a fourth-order power system containing excitation limitation, comprising the following steps:
[0034] Step ①: Establish the mathematical model of the fourth-order power system. When the power system generates chaotic oscillation, determine the value of each parameter in the power system. The mathematical model of the fourth-order power system is formula (1):
[0035]
[0036] Among them, δ is the relative angle of the generator rotor; ω is the relative angular velocity of the generator rotor; E′ is the transient potential of the generator stator side; E fdr is the input of the excitation limiter; M is the moment of inertia of the generator; f 0 is the system voltage frequency; D is the damping coefficient of the generator; P T is the mechanical input power of the ...
