Abstract: There are errors in measurement and data acquisition in electricity marketing, which impact electricity cost accounting and energy conservation efforts. This study focuses on the issue of metering acquisition errors in power marketing, analyzing error types and causes from the perspectives of equipment, environment, and human factors. A quantitative analysis is conducted, governance solutions are proposed for the core problems, and they are quantitatively analyzed through model building, path analysis, and scenario simulation. Finally, for the two core problems of electromagnetic interference and communication packet loss, the governance solutions of "shielding plus filtering" and "signal enhancement plus data supplementation" are explored. Practical application demonstrates that this scheme significantly reduces measurement collection errors, improves data accuracy and reliability, and provides strong support for electricity cost accounting and energy conservation, which has important practical significance.
