摘要

本文对电力系统规划标准的可管理性、表现力和简洁性进行了研究。标准根据偶然性和以客户为中心以及确定性和概率标准进行分类。给出了一个简短的描述。对若干电压等级从U/sub /=20 kV到U/sub /=380 kV的实际德国电力系统进行了研究。分析和比较了有关网络组件类型和补救措施的几种标准的变化。此外，采用显著性检验方法对所调查的概率指标进行了比较。结果表明，国际上广泛使用的(n-1)准则有时比所研究的以偶然性为中心的概率准则限制性更小。

Valuation of planning criteria in a competitive market

The paper presents an investigation of manageability, expressional force, and conciseness of planning criteria for electrical power systems. Criteria are classified according to contingency- and customer-focused and in deterministic and probabilistic criteria. A short description is given. A number of actual German power systems with voltage levels from U/sub n/=20 kV up to U/sub n/=380 kV are investigated. Several variations of the criteria with respect to the network component types and remedial measures have been analyzed and compared. Additionally, the investigated probabilistic indices are compared by applying a significance test method. The results show that the international, widely used (n-1)-criterion is sometimes less restrictive than the investigated contingency-focused, probabilistic criteria.
