Embodiment Construction

[0018] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] The invention is applicable to the monitoring and evaluation of excitation systems of different power plants and different generators. By providing the parameter list of the generator excitation system, the evaluation index of the module is calculated in real time according to the relevant data of the generator set. Generator excitation system online monitoring and evaluation system is a sub-unit under the application of WAMS. Based on the smart grid dispatching technical support system platform, through the generator excitation system online monitoring and evaluation system, dispatching operators can quickly grasp the various aspects of the generator excitation system. The indicators provide convenience and provide more detailed auxiliary decision-making basis for further analysis of the operation of the generator excitation ...

Abstract

The invention relates to a WAMS-dynamic-data-based on-line monitoring and evaluation system for an excitation system of a generator. The system comprises a generator state monitoring system, an evaluation module of low-frequency oscillator effect suppression effect by an excitation regulator power system stabilizer (PSS), and an excitation regulator restriction and protection motion correctness evaluation module. Real-time calculation and monitoring of a generator operation state index, capability evaluation of low-frequency oscillation suppression by an excitation regulator power system stabilizer (PSS), and on-line evaluation on correctness of excitation regulator restriction and protection motion are realized. According to the invention, with the means of on-line equipment monitoring, a monitoring evaluation platform of a generator excitation system is established; and the generator excitation system operation state is monitored remotely in real time so as to find a factor affecting safe and stable operation of a power grid by a power side timely. Meanwhile, an auxiliary tool and a convenient means are provided for rapid positioning of an excitation system problem by the power gird scheduling operation staff.

Description

technical field [0001] The invention belongs to the field of dynamic monitoring of electric power systems, and in particular relates to an online monitoring and evaluation system of a generator excitation system based on dynamic data of a power grid wide-area measurement system (ie WAMS). Background technique [0002] With the continuous expansion of the scale of the national interconnected power grid, the stability of the power system has attracted much attention. Among them, generator excitation control is one of the most economical and effective methods to maintain a constant machine terminal voltage and a reasonable distribution of reactive power between parallel operating units, and to improve and enhance the stability of the power system. But for a long time, there is a lack of a method system to evaluate the effectiveness of the generator excitation system based on the measured data. [0003] With the development of phasor measurement unit (PMU) and wide area measure...
