Research Of Intelligent Substation Check And Operation

Although smart high voltage equipment has not been used in intelligent substation, but in the low voltage systerm, a lot of smart equipment has been used.Compared with the conventional substation, the method of intelligent substation check and operation is greatly different.With the accelerated pace of intelligent substation spreading, the technology of intelligent substation operation lagging behind, that regard the growing pace of intelligent substation, on the other hand, this lagging bring a threat to the safe and stabl of our electric grid.Compared to converting station,you can not find physical electric circuit of the secondary systerm in the intelligent substation, these contect are unvisible, and can not be measured. Therefore, this paper focus on the research of the intelligent substation check and operation.This paper focuses on solving the bottleneck of intelligent substation check and operation, based on the existing intelligent substation hardware and software background conditions, combined with intelligent substation acceptance and inspection experience in comprehensive study of intelligent substation inspection and transport inspection methods.The Paper systematically studied the acceptance of smart substation secondary circuit method, compared to the extensive use of the characteristics of the optical signals for intelligent substation with conventional substation, focused on the light circuit inspection methods, summed up the fiber optic network layout, you can visually see the light path signal transport inspection for acceptance and intelligent substation has important application value.The paper combines Yang Zhi station SCD document detailing the intelligent substation SV sampling system, GOOSE fiber link system, fault recording system and equipment station control systems and their subsystems FBI, test methods, and acceptance of smart substation transport Unit has a key role in guiding.The paper combines the impact of the main transformer Yang Zhi station power transmission operation, compared to conventional substation operation and maintenance methods, a detailed analysis of the details of the operation and maintenance of intelligent substation, focusing on the precautions to protect investment in smart substation, substation operation and maintenance of reducing accidents important help.The Paper combines the last two years the typical processing power outage and the warning signal, fault analysis on intelligent sunstation details to lessons learned, elaborate methods of example, systematically expounded the intelligent substation transport inspection details.
