在竞争的电力市场中 ,由于各电力公司、电力采办公司、电网公司分属不同的经济实体 ,从而导致在系统运行和规划设计中对系统安全可靠性因素的考虑与传统电力系统存在巨大的区别。文中针对市场环境下电力系统的安全可靠性问题 ,从电网运行、电网规划、电力系统维修、反事故自动装置等几方面进行了探讨。指出 :安全性将融入经济性中 ,传统电力系统中的安全性指标将不再单独存在 ,而只是作为可能给相应公司带来经济利益的一种措施 ;传统电力系统中的某一安全性指标在市场环境下是否会得到执行、执行到何种程度将取决于这一指标的执行是否会给相应的公司带来经济上的好处
In the competing electricity market, because the power companies, power acquisition companies and power grid companies belong to different economic entities, the consideration of system safety and reliability factors in the system operation and planning and design is hugely different from the traditional power system . In this paper, the safety and reliability of power system in the market environment are discussed from the aspects of power grid operation, power grid planning, power system maintenance and anti-accident automatic device. It is pointed out that the security will be integrated into the economy and the safety indicators in the traditional power system will no longer exist alone but only as a measure that may bring economic benefits to the corresponding companies. A certain safety index in the traditional power system Whether or not it will be enforced in a market environment depends on whether the implementation of this indicator will bring economic benefits to the appropriate company
