Abstract

Modern industrial power supply systems are characterized by dynamic operating modes, nonlinear loads, and complex, stringent power quality requirements. Today, developed countries utilize state-of-the-art equipment such as FACTS (Flexible AC Transmission Systems) to improve voltage stability in power supply systems, compensate for reactive power, and suppress oscillations. One example is static thyristor compensators (TSC), known internationally as Static Var Compensators (SVC). This article discusses the operating principle, design, and capabilities of SVCs, as well as examples of their application in both industrial and residential power supply systems. A distinctive feature of this compensator is its use of thyristors, which provides a response time of 10-30 ms, making it an essential system element for increasing voltage stability and improving electromagnetic compatibility. This article presents a detailed analysis of both the theoretical and practical aspects of SVCs, as well as practical applications in real-world applications. By reducing reactive power consumption, SVCs can provide cost savings. Based on operating experience with reactive power compensators, the payback period for SVCs is typically up to one year.
