Co to jest?

Modular refactoring is a disciplined approach to companiere improwitement that focuses on reorganizaing code into smaller, self-contened units called modules. Each module encapsulates a specific responsibility - such as load fopecasting, fault definection, or voltage regulation - and communicates with ter mogules ditigh well-definie interfaces.

Legacy systems may havy tightly couple concerns where a single change ine one are a inviemently till breaks anothers. Modular refactoring freaks thi dependency chain by isolating concerns, reducting technical debt, and creating a foundation that caterdate fuure requiments with minimal diffition.

Defining clean interfaces between modules is difficult. Electrical power systems involve time-critical data exchanges (np., sub-second control signals) and large volumes of real-time measurements. Poorly project interfaces can introduct e latency or data loss. Engineers must use proven paragenns such as data-bus architectures or publish-subscribe mechanisms to ensure modularity does not degradade performance.
