| 摘 要： | 由于投入备自投装置时,没有充分考虑备用电源侧元件热稳定极限的影响或其他相关母线的电压越限情况,导致连锁故障发生,会使故障进一步扩大.在考虑备用电源所在电网的网架结构、运行方式以及负荷水平的条件下,建立了备用电源侧可用输电能力实时在线评估数学模型,并应用重复潮流法,对该模型进行了求解,将所得结果作为备自投装置动作与否的决...

| Abstract: | Cascading failures may occur if the influence of the component thermal stability limits at standby power supply side and the voltage limits of relevant bus is not carefully considered during BATS(Busbar Automatic Transfer Switch) operation.A real-time mathematical model for online assessing the available supply capability of standby power is established with the consideration of network structure,operating mode and load level.The repetitive power flow method is used to solve it and the obtained results are ... |
