Abstract: (2037 Views) |
An important issue with respect to the hydraulic power systems is the frequency stabilization. To design Load Frequency Control (LFC) with high efficiency, control parameters need to be adjusted so that the system frequency remains stable even under changeable conditions. Controlling the frequency and changes in the turbine time constant requires that three term control parameters of Proportional-Integral-Derivation (PID) and Transient Droop Compensators (TDC) in hydraulic power systems be adjusted separately, without considering the damping parameters simultaneously with the load working condition. Owing to the significance of the above issues in hydraulic power systems, this paper aimed to study the adjustment of parameters using the methods of Particle Swarm Optimization (PSO), Desired Time Response Specification (DTRS), and Maximum Peak Resonance Specification (MPRS). The obtained results of simulation revealed that the method of Desired Time Response Specification (DTRS) is superior to the other methods under most conditions considering the frequency deviation and turbine output power.
