摘要

本文介绍了一种基于无源谐波滤波器应用的估算畸变源贡献的新方法。该方法无需测量谐波网络阻抗,而是以测量电网、用户和无源谐波滤波器的谐波电流为基础。使用无源谐波滤波器评估用户的贡献对于选择谐波降低设备的参数和连接点是必要的。该方法的一个特点是,无论背景谐波失真如何,都能正确确定份额贡献。根据这种方法,即使在存在背景畸变的情况下,单个用户也能评估自身负载的谐波贡献,以及在安装谐波抑制装置的情况下的谐波电压畸变。研究结果在实验室条件下得到了证实,电网侧和用户侧均连接了不同组合的电力负载。在这种条件下,所提出的方法与现有方法进行了比较,其中包括基于谐波电压矢量、谐波电流矢量和有功谐波功率测量的方法。以天然气生产领域为例,演示了所开发方法的应用。

Method for determining the harmonic contribution of consumer installations based on the application of passive filters

Method for determining the harmonic contribution of consumer installations based on the application of passive filters

The paper presents a new method for estimating the contribution of distortion sources based on the application of passive harmonic filters. The method does not require the measurement of harmonic network impedance and is based on the measurement of harmonic currents of the grid, consumers and passive harmonic filters. Evaluation of the consumer contribution using a passive harmonic filter is necessary to select the parameters and connection points for harmonic reduction devices. A feature of the method is the correct determination of share contributions, regardless of background harmonic distortions. Based on this method, a single consumer can evaluate both the harmonic contributions of its own loads, even in the presence of background distortions, and the harmonic voltage distortions in the case of installing harmonic reduction devices. The research results are confirmed in laboratory conditions with various combinations of electrical loads connected both at the grid side and at the consumer side. For such conditions, the proposed method was compared with existing methods, among which are methods based on the measurement of harmonic voltage vectors, harmonic current vectors and active harmonic power. The application of the developed method was demonstrated using the example of a gas production field.

期刊介绍: IET Generation, Transmission & Distribution is intended as a forum for the publication and discussion of current practice and future developments in electric power generation, transmission and distribution. Practical papers in which examples of good present practice can be described and disseminated are particularly sought. Papers of high technical merit relying on mathematical arguments and computation will be considered, but authors are asked to relegate, as far as possible, the details of analysis to an appendix. The scope of IET Generation, Transmission & Distribution includes the following: Design of transmission and distribution systems Operation and control of power generation Power system management, planning and economics Power system operation, protection and control Power system measurement and modelling Computer applications and computational intelligence in power flexible AC or DC transmission systems Special Issues.
