When the modern power gird scope expands continually, the security and stability of power system operation become the important question for power gird research in all of world. Especially after several international significant blackouts, many counties attached importance to research for power safe operation and constitute the standard for security and stability. They strengthened the specification and researched from power gird framework to electrical system's relay protection and security and stability.Shengli oilfield power gird is one of biggest corporation power gird in China, it' capacitance is 1000000 kW. This paper according to < Power System security and stability guide rule >, particular analysis and research in actuality for Shengli Oilfield power gird, find out the problem in existence for power gird operation and bring out the power gird frame, put forward the solve project and measure pertinently for power gird frame, optimize power gird system operation, constitute and perfect power gird three safe defense. |
