This dataset focuses on analyzing the impact of harmonic intensity on the tripping characteristics of molded case circuit breakers (MCCBs), and reveals the quantitative relationship between harmonic interference parameters and the protection performance of circuit breakers. It provides critical decision-making support for the company (as a manufacturer) and external stakeholders, and boasts significant application value, which is reflected in the following aspects:
1. Optimize product development and production processes: The company can accurately optimize the electromagnetic compatibility design, harmonic suppression measures and signal processing algorithms of circuit breakers by analyzing the influence of different harmonic intensities on their tripping characteristics, scientifically formulate harmonic interference control standards, and enhance the protection accuracy of circuit breakers in harmonic-polluted power grids.
2. Promote industrial technological advancement: This dataset can offer support to researchers and technical R&D personnel in the circuit breaker industry, assisting them in conducting work such as harmonic characteristic analysis, anti-interference performance prediction and quality control, and promoting the improvement of the intelligent protection capability of circuit breakers in complex power environments.
1. Data collection: Real-time recording of the tripping time test data of molded case circuit breakers under different harmonic intensities, including fields such as "test sample number", "test time", "harmonic intensity (%)", "tripping time (ms)", etc.
2. Data preprocessing
(1) Perform denoising processing on the collected data to ensure data accuracy.
(2) Aggregate all historically collected data (including this batch of collected data) to form dataset X, and calculate the average value of the tripping time field in dataset X.
3. Calculate the linear regression slope a and intercept b
(1) Based on dataset X (taking harmonic intensity as the independent variable and tripping time as the dependent variable), use the SLOPE function to determine the slope a, and use the INTERCEPT function to determine the intercept b.
(2) The slope a represents the degree of influence of a unit change in harmonic intensity on the tripping time, and the intercept b represents the tripping time value of the molded case circuit breaker under the reference harmonic intensity.
4. Result application
(1) Calculate the proportional coefficient k: k = |a / average tripping time| × 100%.
(2) If k ≥ 8%, it is classified as "high impact"; if 3% ≤ k < 8%, it is classified as "medium impact"; if k < 3%, it is classified as "low impact".
