针对大型用户负荷接入后对电网稳定性的影响,提出负荷点每年的故障频率、负荷点每年的故障持续时间、平均供电可用度 3 个可靠性评估指标.在DigSILENT/PowerFactory仿真软件建立各电压等级电网的等值模型,设置大用户变电站近区电网的可靠性参数及停运安排.以某沿海城市大型用户为例,对其投产当年及 5 年后大用户变电站与近区电网的接口变电站的可靠性指标进行仿真计算.结果表明,在新型电力系统背景下对大型用户变电站近区电网的可靠性评估结果可为电网企业开展大型用户接入电力系统方案决策管理提供技术性支持.
Study on Management of Big User Access by Power Grid Enterprises Under New Power Systems
In view of the influence of big user load on the stability of power grid,three reliability evaluation indexes were proposed:annual failure frequency of load point,annual failure duration of load point and average supply availability.In DigSILENT/PowerFactory simulation software,equivalent models of power grids of various voltage levels were estab-lished,and reliability parameters and outage arrangements of power grids in the vicinity of big user substations were set up.Taking a big user in a coastal city as an example,the reliability indexes of interface substations between big user sub-stations and near-area power grids were simulated and calculated in the year of initial operation and five years later.The results showed that the reliability evaluation results of the near-area power grid of big user substations under the back-ground of new power system can provide technical support for power grid enterprises to make decision management for the access of big users to the power system.
