Parameter Computation And Experiment Of Generator Excitation System PSS Of Shuikou Hydroelectric Power Station

After the ShuiKou hydroelectric power station is in1983on the Fujian placeelectrical network delimited the central management first “the country words” theenergy big project, the ShuiKou power station takes the Fujian electrical network’smain force power plant, held the post of the Fujian electrical network peakload, thefrequency modulation, the accent to press with the emergency duty duty, its unit PSSfunction’s correct display to stabilized the Fujian electrical network to play the veryimportant role, the ShuiKou to its governed7power sets to2006to make theexcitation control system transformation, used based on SIMADYN D total characterstyle microcomputer field regulator’s Germany Siemens new generation THYRIPOLexcitation control system, substitution west of family household S5PLC is the coreold system originally, its PSS control System also by hardware PSS independentcontrol transition for software PSS integrated control way.This paper has the low frequency vibration reason to the large-scale electricalnetwork to carry on the theoretical analysis first, obtains realizes as a main forcepower source unit suppresses the important controlling unit which the electricalnetwork low frequency vibration needs to adjust. Afterward, ake the ShuiKouelectricity generation key position’s large-scale water power synchronization powerset (the200MW single plane) fast from the shunt excitation system as an example,carries on the introduction to the electrical network low frequency vibration reasonand the current mainstream solution,then introduced systematically based onSIMADYN-D the total character style controller’s ShuiKou power plant unitexcitation system PSS debugging process, Explain PSS in China research in electricpower project in the production process, along with introduction of SiemensSIMADYN-D control system application in large generator excitation control.This article solves technical question:1st, through the theoretical analysis and thesimulation computation, obtains several groups to satisfy the Fujian-East Chinaelectrical network steady operation request the unit PSS parameter.2nd, completes thePSS parameter input using the programming debugging aids in the excitation SIMADYN-D control system, realizes the software PSS control.3rd, formulationreasonable, safe experimental plan, examines PSS to establish in the actual movementthe performance.All in all, This article obtains the achievement mainly has: first, obtains realizes as a mainforce power source unit suppresses the important controlling unit which the electricalnetwork low frequency vibration needs to adjust. Afterward, introduced systematicallybased on SIMADYN D the total character style controller’s ShuiKou power plant unitexcitation system PSS debugging process, said that has analyzed meets the question,debugged the project practice for the domestic same type unit (the Three Gorges excitationsystem PSS debugging) to provide the reference to use for reference. The sceneperformance test indicated that this article does the work drawing close to practice, and hascertain promoted value.
