Ultra-high harmonic detection in distribution networks relies on advanced technologies designed to measure and analyze harmonics beyond the conventional limits. Here are some key technologies used for ultra-high harmonic detection:
Wideband Spectrum Analysis: This technology involves using wideband spectrum analyzers capable of analyzing frequencies well beyond the conventional range to detect and analyze ultra-high harmonics.
Digital Signal Processing (DSP): DSP techniques are used to process the acquired harmonic signals, extract the relevant frequency components, and perform advanced filtering and analysis.
Fast Fourier Transform (FFT): FFT algorithms are employed to convert the time-domain waveform into the frequency domain, enabling precise identification and analysis of ultra-high harmonics.
High-Speed Sampling: Utilizing high-speed sampling techniques, such as sampling rates in the order of several MHz, allows capturing fine details of the waveform and accurately identifying ultra-high harmonics.
Nonlinear Load Identification: Advanced algorithms and techniques are employed to distinguish between linear and nonlinear loads in the distribution network. This helps in identifying the sources of ultra-high harmonics and targeting appropriate mitigation measures.
High-Frequency Current Transformers (HFCT): Specialized HFCTs capable of sensing and measuring high-frequency components are used to capture ultra-high harmonic currents accurately.
Precision Current and Voltage Sensors: High-precision current and voltage sensors ensure accurate measurement of ultra-high harmonics, particularly in the presence of non-sinusoidal and distorted waveforms.
Power Quality Monitoring Systems: Integrated power quality monitoring systems equipped with advanced harmonic analysis capabilities enable continuous monitoring of ultra-high harmonic levels in real-time.
Adaptive Filtering Techniques: Adaptive filters are used to extract ultra-high harmonic components from the measured waveform, compensating for variations in load conditions and network parameters.
Multiresolution Analysis: Multiresolution analysis techniques, such as wavelet transforms, are applied to characterize and identify ultra-high harmonics across different frequency scales.
These technologies collectively contribute to the accurate detection, analysis, and monitoring of ultra-high harmonics in distribution networks, enabling effective mitigation strategies to maintain power quality and avoid adverse effects on the electrical infrastructure and connected equipment.
