中文摘要:

混合风电场集成了风力发电、太阳能发电等多种可再生能源。这些能源输出的间歇性与波动性会致使电网能量分布失衡,威胁电网安全稳定运行。基于此,本研究聚焦于能量均衡性控制,对混合风电场新型低压配网安全系统展开探讨。硬件设计上,引入储能系统以平衡和抑制风电场并网时的能量波动,并构建配网结构框架；同时运用能量均衡性控制技术构建时钟树配置模块,保障配网信号实时转换,优化发电 - 负荷匹配,减少频率波动,提升电网频率稳定性。软件设计方面,首先依据等效原则深入剖析风电场配网的电压 - 电流关系,然后基于能量均衡性控制策略构建电压 - 电流保护矩阵,优化系统安全性。实验环节以国内某风电场为例,针对其日内输出功率不平衡状况进行测试,结果显示该系统可补偿输出功率差值,满足稳定并网需求,具有重要应用价值,既能丰富混合风电场安全控制理论,又能为实际风电场安全运行提供技术支撑。

英文摘要:

A hybrid wind farm integrates various renewable energy sources such as wind power and solar power. The intermittency and volatility of these energy outputs can lead to an imbalance in energy distribution in the power grid, posing a threat to the safe and stable operation of the power grid. Based on this, this study focuses on energy balance control and explores a new low-voltage distribution network safety system for hybrid wind farms. In terms of hardware design, energy storage systems are introduced to balance and suppress energy fluctuations when wind farms are connected to the grid, and a distribution network structure framework is constructed; Simultaneously utilizing energy balance control technology to construct a clock tree configuration module, ensuring real-time conversion of distribution network signals, optimizing generation load matching, reducing frequency fluctuations, and enhancing grid frequency stability. In terms of software design, firstly, based on the principle of equivalence, the voltage current relationship of wind farm distribution network is deeply analyzed. Then, based on the energy balance control strategy, a voltage current protection matrix is constructed to optimize system safety. The experimental section takes a domestic wind farm as an example to test the imbalance of its daily output power. The results show that the system can compensate for the difference in output power, meet the stable grid connection requirements, and has important application value. It can enrich the safety control theory of hybrid wind farms and provide technical support for the safe operation of actual wind farms.
