摘要：分散而斷續(xù)的發(fā)電是電力產(chǎn)業(yè)變化的一個重要發(fā)展方向，隨著新能源的發(fā)展使電網(wǎng)變得更加復(fù)雜，微電網(wǎng)便是其中之一。微電網(wǎng)是由風(fēng)、光等發(fā)電裝置，加上開關(guān)電源變流器、由PC等控制器進(jìn)行管理，與市電網(wǎng)并聯(lián)后形成雙電源、雙向能流，并能完善運行、保護(hù)的小型電力系統(tǒng)。本文系統(tǒng)闡述了微電網(wǎng)的發(fā)展、含義、特征、運行和控制,重點對微電網(wǎng)變流器工作原理進(jìn)行論述。 敘詞：微電網(wǎng)/模型/XX電力電源/開關(guān)電源變流器/實驗平臺指標(biāo) Abstract：Disperse and intermittent power generation is an important direction of the development of power industry. As the rise of new energy makes grid more complex, microgrid turns up. It is a small, perfect-operating-and-protecting power system managed by controllers like PC and paralleled with city grid to form double power and dual energy flow, which combines wind and PV generating apparatus with switching power converter. This paper systematically introduces its development, definition, features, operation and control, focusing on the analysis of the operating principle of microgrid converter.
