摘要
虽然太阳能面板或太阳能模块是太阳能系统的核心,这些是较为明显的部分。但在整个信号链中,更复杂的部分是光伏逆变器—控制系统的大脑。光伏逆变器需要经过仔细设计,以保护电流测量和计算电路,使其不受功率处理电路以及开关所引起的瞬态信号影响。这种保护代价不菲,多个冗余隔离器件会提升成本和系统复杂性。而且很明显,通过可编程处理器来运行这些系统所需的日益复杂的算法,需要考虑代码完整性以保证系统自身的安全性问题。
Because the solar panels or solar modules are the core of the solar system, these are more obvious parts. But in the whole signal chain, the more complex part is the brain of the inverter control system. The inverter should be carefully designed to protect current measurement and calculation circuit, so that it is not affected by transient signal caused by power processing circuit and switch. This kind of protection which is expensive, and multiple redundant isolation devices, will increase the cost and complexity of the system. Moreover, it is obvious that the increasingly complex algorithm needed to run these systems through programmable processors needs to consider code integrity to ensure the safety of the system itself.
