基于光伏模块直流物理模型，在matlab 仿真环境下，开发了光伏阵列通用仿真模型。利用该 模型，可以模拟任意太阳辐射强度、环境温度、光伏模块参数、光伏阵列串并联方式组合下的光伏阵 列I-V 特性。此外，该模型还融合了光伏阵列的最大功率跟踪（MPPT）功能，可以用于光伏发电系统 和风光复合发电系统的动态仿真。(A Versatile simulation model for photovoltaic array is developed based on the DC physical model of photovoltaic module under Matlab environment. By the model，the I-V characteristics of photovoltaic array with different combinations can be simulated at any corresponding insolation level, ambient temperature and parameters of the photovoltaic module. In addition to that, the model includes the function of Maximum Power Point Tracking(MPPT) . It can be used in the dynamic simulation of photovoltaic systems and wind-solar hybrid systems.)

说明：  RS码(Reed—Solomon码)是多进制BCH码，也是目前最有效、应用最广泛的差错控制编码。它具有很强的纠错能力，随机错误、突发错误都能纠正，特别是在短的和中等码长其性能接近于理论值。再加上构造方便，编码简单，设备不复杂，因此在实时性要求较高的数字通信及深空通信方面有广泛应用(RS code ( Reed- Solomon code ) is a multiple of BCH code, is currently the most effective, the most widely used error control coding. It has a strong error correction ability, random error, burst error can be corrected, especially on short and medium length code performance close to the theoretical value. Plus convenient construction, simple coding, equipment is not complex, so the real-time digital communication and deep space communication is widely used )
