Parallel Path Flow, also referred to as loop flow, unscheduled power flow, or circulating power flow, is a phenomenon observed in power transmission systems. It occurs when power flows along multiple parallel paths, and the actual flow differs from the scheduled flow on a transmission path. In this path flow, the discrepancy between scheduled and real power flows is primarily influenced by the resistance of each path.
In a transmission system, the power flow along parallel paths is inversely proportional to the resistance of each path. Parallel-path method demands that if a path has lower resistance, it will carry a greater proportion of the power flow compared to a path with higher resistance. This characteristic highlights that the distribution of power across parallel paths depends on the relative resistances involved.
Why Parallel-Path Method is Important?
Additionally, the concept of the parallel-path method extends to the context of heat transmission. In this context, it assumes that the portion of heat transmitted through a less resistive path, typically involving materials with higher conductivity like a stud, remains parallel from the indoor wall to the outer surface. This assumption in parallel path connection aids in analyzing and managing the distribution of heat or energy in systems with parallel paths, such as insulation or thermal conductivity analysis. It helps in the overall system behavior, voltage stability, and power flow distribution and prevents overloading.
