摘要
为消纳新能源发电带来过剩的电力能源,保证系统频率稳定,研究在新能源发电并网下的频率与负荷变化关系是必要的。介绍了系统频率与负荷之间的变化关系即一次调频基本原理,对实际电力系统某一大规模电网频率与负荷功率等相关数据进行采集,了解在系统不同负荷下频率如何变化以及连续量时刻内的不平衡功率对系统频率的影响关系表达式,分析该电网下负荷与频率变化关系,以加强对大电网的掌控能力以及突发事故的调控能力。
In order to absorb the excess electric energy brought by new energy power generation and to ensure the stability of the system frequency,it is necessary to study the relationship between frequency and load changes under the grid connection of new energy.The relationship between system frequency and load is introduced.The relationship of change is the basic principle of primary frequency modulation.It collects related data such as frequency and load power for a large-scale power grid in the actual power system to understand how the frequency changes under different loads in the system,and the unbalanced power in the continuous amount of time affects the system expression of the influence relationship of frequency.It analyzes the relationship between the load and frequency change of the power grid,so as to strengthen the control ability of the large power grid and the control ability of sudden accidents.
