Control & Protection Studies
Comprehensive analysis and design of control systems and protective devices for reliable power system operation
What are Control & Protection Studies?
Control & Protection (C&P) studies encompass the comprehensive analysis, design, and coordination of control systems and protective devices in power systems. These studies ensure reliable, safe, and efficient operation of electrical networks under normal and abnormal conditions.
Modern power systems require sophisticated control and protection schemes to handle complex interactions between conventional and renewable energy sources, maintain system stability, and protect equipment from damage.
