澳大利亚长期国家电能质量调查 (LTNPQS) 是一项大型多公用事业电能质量调查，现已运行 8 年。本文详细介绍了为 LTNPQS 开发的报告和分析程序的最新创新进展。该文件还强调了目前影响澳大利亚电网的关键电能质量问题。其中包括低压站点的高电压水平以及电压不平衡测量的困难。调查的长期性使人们能够更好地了解干扰趋势水平。有趣的结果包括过去几年谐波水平明显下降，并且即使有 7 年的数据，电压骤降水平也没有明确的趋势。探讨了进行此类调查所涉及的一些挑战，并提出了解决方案。随着智能电网概念的实施，配备能够为调查提供数据的仪器的站点数量可能会呈指数级增长。这提出了一系列新的挑战，调查必须适应这些挑战。未来的应对方向包括实施基于网络的报告系统，这将为参与者提供更大的灵活性。
The Australian Long Term National Power Quality Survey (LTNPQS) is a large multi-utility power quality survey which has now been in operation for 8 years. This paper details the latest innovative developments in the reporting and analysis procedures developed for the LTNPQS. The paper also highlights the key power quality issues affecting Australian electricity networks at the present time. These include high voltage levels at LV sites and difficulties in measurement of voltage unbalance. The longevity of the survey has allowed better understanding of disturbance trend levels. Interesting results include an apparent reduction in harmonic levels in the past couple of years and no definite trend in sag levels even with 7 years worth of data. Some of the challenges involved in conducting a survey of this type are explored and indications as to solutions presented. With the implementation of smart grid concepts it is likely that the number of sites with instrumentation capable of supplying data to the survey will increase exponentially. This presents a new set of challenges and the survey must adapt to these. Future directions taken in response include the implementation of web-based reporting systems which will provide more flexibility for participants.
