HARMONICS IN RELEVANT LEGAL DOCUMENTS FOR ELECTRIC POWER SYSTEMS OF VIET NAM

Abstract

Harmonics (including interharmonics) in particular and power quality in general are increasingly concerned in the context of the power system with more and more power generation sources connected through power electronic converters. In order to ensure the technical requirements for the power system, the loads or power generation sources connected to the power system must always response the limits on harmonics that arise specified in relevant legal documents. This paper provides an overview of the relevant regulations in harmonic control in the power system being applied in Vietnam reffered to international standards. The paper would be a reference source for divisions compiling standards and regulations on harmonics in particular and power quality in general in the power system. It will also contribute to improving the service quality of the power system, ensuring quality, safety and efficiency of power supply
