摘要:

现代工业园区具有用电量大、敏感设备多、电压等级高等特点,为缓减电压暂降对现代工业园区用户造成的巨大经济损失,克服现有治理方案手段单一、成本高以及可实施性差等不足,提出协调采用电网侧和用户侧治理措施、优化配置切换型与补偿型治理设备的电压暂降综合防治方案。首先,对用户侧多个同类型与不同类型暂降治理设备的性能、成本进行分析,建立各治理设备的成本模型;其次,对输配电线路的改造成本分别进行建模,并建立线路改造后园区年度暂降次数模型;最后,建立综合防治后治理方案的最大净现值目标函数,利用粒子群优化算法求解获得园区最优的暂降治理设备配置方案。通过对某现代工业园区进行实例分析,验证了该方案能综合应用各种治理手段,提高园区电压暂降治理的净现值,具有较好的可行性。

Abstract:

The modern industrial park has the characteristics of large power consumption, considerable number of sensitive equipment and high voltage level. In order to mitigate the huge financial losses due to voltage sags, and overcome the shortcomings of single measures, high cost and poor feasibility of existing control schemes, a comprehensive prevention and control scheme for voltage sag is proposed to coordinate control measures on the grid and user sides, and optimize the configuration of switching-type and compensation-type control equipment. Firstly, the performance and cost of the same and different types of control equipment on the user side are analyzed, and the cost model of each control equipment is established. Secondly, the reconstruction cost of transmission and distribution lines are modeled separately, and then the annual voltage sag times of the park after reconstruction is modeled. Finally, the objective function of the maximum net present value of comprehensive prevention and control scheme is established, and the particle swarm optimization algorithm is used to solve the optimal configuration scheme of control equipment in the park. Through an example analysis of a modern industrial park, it is proved that the scheme can apply various control means comprehensively to improve the net present value of voltage sag control in the park, and has a good feasibility.
