Abstract : Deregulation in power system results in separate entities like generating company, distribution company, transmission company and independent system operator. The reliability and stability of the system is the responsibility of the independent system operator that provides many ancillary services, one of which is load frequency control. In a deregulated power system, the GENCOs generate to meet the contracted demand of the distribution companies via load frequency control. This paper presents a hardware development of control strategy and its integration with the single area deregulated load frequency control model in LabVIEW. The transfer function model of the deregulated single area system is modeled in LABVIEW. The secondary controller (Integral controller), responsible for maintaining the frequency at nominal value is developed in ARM processor and is interfaced with LABVIEW. The proposed system is tested for the effectiveness of the developed controller during contracted condition and demand violation.
