Description

Apparatus and Method for Establishing Strategy of Asset Management The present invention relates to an apparatus and method for establishing an asset management strategy. Generally, power facilities assess their current condition and implement corrective measures through asset health assessments. The items used for asset health assessment are called the Asset Health Index (AHI) and are defined in technical documents such as those from the International Council on Large Electric Systems (CIGRE). Currently, various soundness assessment methods, such as simple score summation and weighted score summation, are used as needed. The simple score summation method is a method of calculating a soundness index by assigning an evaluation grade to each component of power facilities for each evaluation item, assigning a soundness score based on the evaluation grade of the item, and summing them up. In this case, the evaluation items may be various inspection/analysis data, and may include, for example, statistical data such as insulation quality, aging degree, and frequency of defects; condition data; operational data; equipment age; equipment installation environment items; appearance inspection items; and characteristic measurement items such as voltage and current. Evaluation grades are typically divided into five levels (very high, high, normal, low, very low), and it can be understood that the lower the evaluation grade level, the higher the probability of failure of the corresponding component. Health scores are assigned as 4, 3, 2, 1, and 0 depending on the evaluation grade. Ultimately, health scores are calculated for each evaluation item and summed to determine the health index, but this method has limitations in that it can only verify the overall health (condition) of the entire power facility, and thus cannot identify the existence of items with low condition evaluation grades—that is, items that are likely to fail if urgent measures are not taken—based solely on the health index. The weighted summation method assigns weights to the simple summation method, assigning higher weights to evaluation items that are more important. Weights can be values between 0 and 1 (inclusive), and the method is set so that the sum of all weights equals 1. However, this weighted summation method also has the limitation that it cannot confirm the existence of items with low status evaluation grades. The indexed score summation method calculates a soundness index by indexing and summing the soundness scores from the simple score summation method, assigning higher scores as power facilities become less sound. However, even with the use of this method, there is a limitation in that it cannot determine whether emergency measures are necessary. As such, while conventional methods for evaluating the health of power facilities calculate individual health indices, they share a common limitation in that they are restricted in verifying the facility's condition using these calculated indices. Furthermore, conventional methods require specialized knowledge in the relevant field, and problems arise in that the results can vary depending on the person evaluating and judging the health.
