基于损耗分配方法的风电场等值建模
摘要：在涉及风电机组集群建模的情况下,由风能的随机性导致的实时变化会增加额外的计算量,从而延长仿真所用时间。本文针对辐射型网络的风电场,提出了一种经由功率叠加和损耗分配的简化等值模型。该模型在已知风电场各台机组功率及线路长度等参数的情况下,将风电场简化为少量机组并联形式的模型,以简化前后风电场内部线损相等为原则进行线路变换,同时满足风电场出口处的有功功率、暂稳态电压幅值及波形稳定的目的。仿真结果显示,该等值模型较好地模拟了风电场内部的运行情况,达到了预定的等值效果,并具有较高的精度。
Abstract:As to the modeling of wind power units, real-time changes caused by the randomness of wind energy will introduce huge calculation amount, which extends the simulation time. In this paper, as to wind farm with radiant network, a simplified equivalent model is put forward through power superposition and loss allocation. This model simplifies multi-unit wind farms into one with parallel connection of a small amount of units under the condition of such known parameters as unit power and line length in the wind farm, which conducts line conversion with the principle of equivalence for internal line loss in the wind farm before and after simplification, and meanwhile meets the stability requirement of active power, transient and steady-state voltage amplitude and waveform at the exit of the wind farm. The simulation result shows that this equivalent model well simulates the internal operation of wind farm, and achieves the expected equivalent effect and has high precision.
