Problems solved by technology

However, the stability of the power system is essentially a global issue. Although the use of decentralized control measures that do not contain global information can improve the stability of the system to a certain extent, it does not directly contain global feedback information that is closely related to stability. This control is indirect and its effectiveness will be constrained

Abstract

The invention discloses a dynamo nonlinear control system based on synchronized phasor measurement technology and a method thereof. The control system of the invention comprises an information bus 2; an information output interface of a global positioning system 1 is connected with the information bus 2; a substation PMU 3 and a control centre station 4 are connected with the information bus 2 via a communication interface; a data output end of the substation PMU 3 is connected with a local controller 5. The invention has the control method that the global positioning system 1 transmits a time signal to the information bus 2 via the information output interface; the substation PMU 3 synchronously transmits the information to the information bus 2; the control centre station 4 synchronously treats and stores the time signal of the global positioning system 1 and the signal of the substation PMU 3 from the information bus 2 via the communication interface; then, the treatment result is transmitted to the substation PMU 3 first, and the substation PMU 3 transmits the information to the local controller 5, which better improves the dynamical quality of a power system as well as drastically improves the stability of the power system.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a generator nonlinear control system based on synchronized phasor measurement technology and a control method thereof. Background technique [0002] The excitation and valve integrated feedback control of the power system has made a lot of valuable progress, especially the application of modern nonlinear control theory in the power system, the design of various nonlinear controllers emerges in an endless stream, which significantly improves the dynamics of the power system. quality, improving the stability of the system. However, looking at these nonlinear controllers, most of them are designed based on the single-machine infinite system model. It is a local state quantity, and its structure can only be a kind of decentralized control that does not contain global information. [0003] The modern power system is a high-dimensional, multi-variable, highly nonlinear, and s...
