海洋平台电缆参数重取对电压稳定评估的影响
The Influence of Submarine Cable Parameter Modification on Voltage Stability Assessment of Offshore Platform
摘要: 海洋平台电网之间都采用海底电缆传输电能，构成完全基于电缆的独立微网系统。但海底电缆参数会随运行情况发生变化，且与出厂参数区别较大，从而影响平台电网稳性评估等计算的准确性。本文通过考虑平台电网边界关联影响，利用平移变换和时间加权回归方法，实现海底电缆参数的重取，进而提高平台微网电压稳定性分析计算的准确度。通过渤海某实际海洋平台群微网的仿真，验证了本文提出方法的准确性，且该方法只需要各平台电网本地运行参数，降低了互联平台间的通信和计算负担。
Abstract: Submarine cables are used for power transmission between offshore platforms, but their para-meters may change according to the operation condition, which may affect the evaluation of power grid stability. This paper focuses on the influence of submarine cable parameters modification on voltage stability assessment and voltage stability models of platforms were established based on L index, with the improved REI equivalence method. Based on the analysis result, the influence of submarine cable parameters modification can be confirmed.
