description |
This paper offer a research experiment of passive detection method based on variation of
two parameters at point common coupling (PCC) which are voltage and frequency during
pre-islanding and islanding. THD of voltage and current parameters are analyzed to
identify the impact towards islanding detection method. Islanding is detected by
considering three type of variation parameters which are increment percentage,
depreciation percentage and rate of change for all parameters mentioned above within two
seconds. The main objective of this project is to implement passive detection method using
voltage and frequency parameters at Point Common Coupling (PCC) as variable
parameters. In this project, PCC is defined as node between output of solar inverter and the
grid supply. Those parameters will be analyzed at PCC during islanding. Throughout this
research, the output voltage and frequency ay the inverter are analyzed to identify the
effectiveness of passive detection method. In addition, the objective of this research is to
identify the impact of total harmonic distortion (THD) of voltage and current parameters
using passive detection method. Next, the research methodology will have five different
phases to achieve the objectives where in early stage it required to identify different
parameters to be using in passive detection method. Next, this research required to develop
experiment method by determine circuit configuration to integrate between solar inverter
with power grid. In 3rd & 4th phase, the data were collected and validated by comparing the
trends with other experiment finding. In final steps, all the data were analyzed and interpret
by calculating the rate of change and percentage of depreciation and increment. For the
result, voltage variation during islanding show a significant of result. However, along the
experiment, frequency result didn’t show any significant of trend to analyze the islanding
in 2 seconds of period. Therefore, total harmonic distortion (THD) of voltage and current
is analyzed if both parameters could give impact to islanding detection method using
passive detection method. Based on the result, the THD of voltage and current trends
showed a significant trend of data to identify the islanding. In this experiment, the variation
of all parameters during islanding are calculated by using increment percentage, decrement
percentage and rate of change in specific period of change. Through these parameters, the
trends indicate to detect islanding phenomena. |
