[Abstract]:Taking voltage sag and harmonic as examples, this paper analyzes the sensitivity and tolerance of user equipment to power quality in high quality power park, and discusses the mechanism and characteristics of power quality disturbance. Firstly, according to the current situation of power quality, the types and capacity of sensitive load and polluting load in the demonstration park, from the power supply capacity, load sensitivity, power quality grade demand and so on, the layout scheme of customized power plant is put forward. The function and performance index are designed, and a comprehensive solution to meet the needs of all kinds of customers in the high quality electric power park is put forward. Secondly, the modeling technology of the main power quality control equipment, such as SSTSX DSTATCOMUPQC and so on, is studied, and the simulation model of the power quality management scheme in the park is established. The results show that the high quality power park can greatly improve the power supply quality of sensitive users. Based on the characteristics of power quality management in high quality electric power park, combined with mathematical theory deduction, this paper uses AHP to select indexes from four angles of energy saving benefit, economic benefit, environment benefit and social benefit. A comprehensive benefit index system including 4 secondary indexes and 16 third-level indexes was constructed. The structure and detailed display of the index system are given, and the detailed significance of each index is explained. Furthermore, the comprehensive benefit evaluation method of power quality control in high quality electric power park is put forward. Based on the comprehensive evaluation theory, several power quality control schemes are treated to calculate the comprehensive benefit related indexes, and the evaluation values of each sample are obtained from the comprehensive evaluation of each index. Through the comparison of evaluation value, we can realize the comparison of the comprehensive benefit of each scheme. The comprehensive evaluation process includes four steps: normalizing the index data, determining the index weight, constructing the evaluation model and displaying the evaluation results. Finally, an empirical analysis of the comprehensive benefit evaluation of power quality management is carried out based on the actual data of the demonstration and application of a high quality power park in China. The results verify the validity and applicability of the index system and the comprehensive evaluation model.
