Abstract

This paper deals with an enhanced phase locked loop with generalized filtering (GF-EPLL) based control algorithm for a grid interfaced solar photovoltaic (SPV) system. The interface between the SPV array and the grid is realized by a voltage source inverter (VSI). The VSI is implemented for SPV power extraction at high power quality and to feed it into the grid and load connected to it. The IC (Incremental Conductance) based MPPT (Maximum Power Point Tracking) algorithm provides the peak power extraction from a SPV array at various environmental conditions. The GF-EPLL based control algorithm is implemented for harmonics elimination and load compensation for power quality enhancement. The phase compensation is introduced in the GF-EPLL algorithm to enhance the transient response of the system. To demonstrate the performance of proposed single stage SPV system, extensive tests are carried out on a prototype of it in the laboratory.

基于广义滤波的EPLL在单相电网接口SPV系统中的实时实现

研究了一种基于广义滤波的增强锁相环(GF-EPLL)的并网太阳能光伏系统控制算法。SPV阵列与电网之间的接口由电压源逆变器(VSI)实现。VSI用于SPV在高功率质量下的电力提取，并将其馈送到电网和连接到电网的负载中。基于增量电导的最大功率点跟踪(MPPT)算法提供了SPV阵列在各种环境条件下的峰值功率提取。实现了基于GF-EPLL控制算法的谐波消除和负载补偿，提高了电能质量。在GF-EPLL算法中引入相位补偿，增强了系统的暂态响应。为了证明所提出的单级SPV系统的性能，在实验室对其原型进行了广泛的测试。
