传统变电站接入燃料电池发电系统的动态特性

Dynamic Characteristics of Connecting Traditional Substations With Fuel Cell Generation System

随着电力市场的发展和各界对能源问题的日益关注,大电网与分布式电源相结合的方式愈受青睐。探讨将燃料电池发电系统接入传统电力变电站后的动态特性,在燃料电池发电原理和详细数学模型的基础上,仿真比较了不同容量燃料电池发电系统的动态性能,及其对配电系统的影响;并分析了燃料电池对变电站负荷波动的响应,测试出它在提高电力系统的负荷跟踪运行能力、减小系统旋转储备和增强系统稳定性等多方面的优点。

With the development of the electricity market and the attention paid to energy problem, the mode by which power grid combines with distributed generation is in good graces, In this paper the dynamic characteristics after the connection of fuel cell generation system with traditional substation is researched. On the basis of power generation principle of fuel cell and its detailed mathematical model, the dynamic characteristics of fuel cell generation systems with various capacities are compared and their impacts on distribution system. The response of fuel cell generation system to the power load fluctuation of substation is analyzed, and the advantages of fuel cell generation system, such as the ability to improve load following operation ability of power system and the reduction of system spinning reserve and enhancement of power system stability and so on, are tested.
