摘要

本文重点研究了电力系统稳定器(PSS)集成三不等面积多源系统的负载自动频率控制与自动调压相结合模型的性能。该系统具有合适的发电速率约束和调控死区以及时滞。针对该模型提出了分数阶PIADF控制器,并与其他经典控制器的性能进行了比较。采用闪电搜索算法对控制器和PSS参数进行同步优化。研究结果表明,PIADF的性能优于整数阶控制器。系统非线性的影响分析表明,响应的持续振荡增加。对PSS的性能进行了研究,结果表明PSS的加入减少了系统的振荡,从而提高了系统的动力学性能。灵敏度分析证实了PIADF控制器的鲁棒性和基本条件下得到的PSS参数。

Performance Analysis of Combined ALFC and AVR System Incorporating Power System Stabilizer
This study highlights the performance of the combined automatic load frequency control and automatic voltage regulator model of Power System Stabilizer (PSS) integrated three unequal area multi-source system. The system is provided with suitable generation rate constraints and governor dead band along with time delay. Fractional order PIADF controller is proposed for this model and compared the performance of the same with other classical controllers. The controller and PSS parameters are optimized simultaneously using lightning search algorithm. The investigation reflects the superior performance of PIADF to integer order controllers. Analysis of the effect of system nonlinearities shows the increased sustained oscillations of the responses. The performance of PSS is investigated and reveals that the inclusion of PSS reduces the system oscillations, which leads to better system dynamics. Sensitivity analysis established the robust performance of PIADF controller and PSS parameters obtained at base condition.
