“…It uses a generalized and theoretically supported formulation of the harmonic Norton equivalent modelling of non-linear branches with simplified harmonic coupling, and states that there is no requirement for analytical formulation of non-linear branch characteristics or pre-calculated knowledge of fundamental frequency behaviour. Another generalized harmonic balance method for EMTP initialization for the steady-state analysis of power system models is reported in Reference [72]. In Reference [73], a new frame of reference for harmonic analysis of power system has been described.…”

SUMMARYThe increased use of power electronic controlled equipment, such as variable speed drives, automated production lines, personal computers and non-linear electronic devices in power systems has given rise to a type of voltage and current waveform distortion called as 'harmonics'. Harmonic can be defined as the undesirable components of a distorted periodic waveform whose frequencies are the integer multiples (non-integer multiples in case of inter-harmonics, and the frequency less than fundamental frequency in case of sub-harmonics) of the fundamental frequency. Presence of these harmonics results in increased losses, equipment heating and loss-of-life, and interference with protection, control and communication circuits as well as customer loads. The research has been underway since very beginning for control of power system harmonics and to supply consumers with reliable and 'clean' fundamental-frequency sinusoidal electric power that does not represent a damaging threat to their equipment. This paper, therefore, reviews the progress made in power system harmonics research and development since its inception. Attempts are also made to highlight the current and future issues involved in the development of quality and reliable electric power technology for future applications. A list of 145 research publications on the subject is also appended for a quick reference.

“…Consequently, three‐phase load flow should be used for electromagnetic transient (EMT) initialisation. To improve the accuracy of the initialisation of EMP model, harmonic load flow is can be adopted [1–3]. Newton–Raphson and fixed‐point‐iteration method are both applicable for ADN load flow [4, 5].…”

“…Nele, o estado inicial requisitado para simular qualquer fenômeno transitório é o sistema de potência não-linear operando em regime permanente. O método do balanço de harmônicos é o preferido nesta área [8]- [10]. No entanto, este método não é adequado para simular conversores de potência pois as formas de onda de regime permanente contêm harmônicos.…”

Resumo-Neste trabalho é apresentada uma técnica para simular as respostas de conversores de potência em regime permanente. Ela é baseada na representação dos elementos do circuito por matrizes impedância ou admitância a partir de formas de onda periódicas. O método de Newton-Raphson é então utilizado para solucionar as equações dos circuitos não-lineares. Modelos detalhados de dispositivos semicondutores podem ser facilmente incluídos no processo. As respostas de conversores eletrônicos de potência típicos são calculadas e suas formas de onda são apresentadas. A técnica desenvolvida também é capaz de simular as respostas de circuitos autônomos e não-autônomos. Palavras-Chave-Circuitos Não-lineares, Resposta em Regime Permanente, Simulação de Conversores de Potência.
