Harmonic detection system and harmonic processing system

Abstract

The invention provides a harmonic detection system and a harmonic processing system, and relating to the technical field of new energy power generation. A wind speed analysis module and a new energy unit analysis module are comprised. The wind speed analysis module is used for analyzing acquired wind speed data to acquire the wind speed and the wind speed type, and extracting first harmonic law information and second harmonic law information from a first package module and a second package module according to the wind speed and the wind speed type. The new energy unit analysis module is used for analyzing the information of a new energy unit to acquire the unit type, proportion and capacity, and extracting third harmonic law information from a third package module according to the unit type, proportion and capacity. On the basis that the wind speed condition or the information of the new energy grid-connected unit is known in a future period, harmonic characteristics in the systems canbe acquired in advance.

Description

technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a harmonic detection system and a harmonic processing system. Background technique [0002] As an inexhaustible clean and non-polluting renewable energy, wind energy has made the installed capacity of wind turbines in my country rise rapidly. At the same time, the installed capacity of wind farms is also increasing, and the impact on the system is becoming more and more obvious, which brings serious power quality problems of wind farms to the grid. [0003] At present, the harmonic detection method of wind power system is usually applicable to the detection of harmonics in the operation of wind farms. Then take active power filter or hybrid power filter for corresponding harmonic compensation. The existing harmonic processing in the wind power system is based on the completion of the wind farm, and the harmonics of the wind farm under different operating con...

AI Technical Summary

Problems solved by technology

In the design stage of the wind farm connected to the grid, the harmonic distribution cannot be predicted and corresponding compensation cannot be performed. Then the equipment transformation and detection and compensation projects invested in the later stage will bring time-consuming, labor-intensive and money-consuming situations, not only the operation efficiency is low. , will also bring a lot of economic losses, which limits the development of the wind power industry to a certain extent
