Feature: Components
environments, such as dust-prone or humid areas, can accelerate failures like contact degradation and sensor malfunctions that stem from electrical stress and inadequate maintenance. Proactive maintenance and access to
spare obsolete components can mitigate these risks, such as component aging and scarcity, forming the basis of an effective obsolescence management strategy.
Critical failures in critical components Failures of critical components in synchronous machine control systems can lead to significant damage and operational disruption. For example, a malfunctioning excitation module can cause unstable voltage output, leading to potential damage to the machine and connected systems. Protection relay failures might allow faults to go undetected, risking catastrophic equipment damage. AVR failures can also
result in voltage instability that can affect the entire power supply system. Tese issues contribute to unplanned
downtime, disrupting operations and incurring substantial repair costs. Te financial implications include lost production, emergency repair expenses and potential penalties for failing to meet power supply agreements, showing the need for proactive spares holding. Overhauling a system with entirely
new components can be prohibitively expensive, involving high upfront costs and extended downtime for installation. In contrast, sourcing replacement of obsolete components from companies like EES offers a cost-effective alternative. Replacement of failed components allows the continued use of existing systems and infrastructure with minimal disruption and lower costs, ensuring the full lifetime of synchronous machines without the substantial investment required for
complete system overhauls. Given the long lifespans of power
plants, proactive obsolescence management is essential to eliminate the risk of a component failure becoming a catastrophe. Access to a reliable inventory of spare parts is crucial for uninterrupted operations and cost mitigation. Cooperation with an expert engineering partner ensures that backup parts are available when needed, reducing downtime and assuring the operational life of synchronous machine systems.
