Problems solved by technology
[0002] The traditional monitoring of the operation status of important users only realizes the monitoring of the power supply on the user distribution network side. Due to the lack of main network path information, it is impossible to monitor the power supply status of the main network power supply, and it is impossible to provide important users with integrated transmission and distribution. Highly reliable operation risk analysis and early warning

Embodiment Construction
[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0019] According to the risk analysis method of the hierarchical operation of the guaranteed power supply area based on the integration of the main distribution network, the integrated model of the main distribution network and the real-time operation mode are obtained first, and the power supply path of the target device is searched through the network topology analysis, and the power supply path search is based on the connection relationship of the equipment As well as power flow information, count all the primary equipment on the power supply path, find the backup power point of the bus with different voltage levels, obtain the power supply configuration information of different voltage levels on the power supply path, combine the power supply risk expert database, and evaluate the risk of the power guarantee user grade.

The invention discloses a risk analysis method based on the integration of main and distribution areas for power supply protection in different grades. Based on the integration of main and distribution models, the search for the power supply path of the power supply users in the entire network is realized, and the differences in the power supply configuration principles of users in the same area and the Relevant basis for risk grading, building a power supply loss risk rating expert database, analyzing the redundant configuration of power supply points of different voltage levels for power guarantee users, evaluating the risk of power loss for power guarantee users, and realizing the risk analysis of the graded operation of the main power supply integrated system guarantee power supply area . At the same time, based on the real-time power grid status, it can dynamically extract the set of power supply path devices through topology services, and automatically display the power supply paths and power supply risks of power conservation users in a tree layout. The method of the invention can assist dispatching and operating personnel to control the power supply situation of power-guaranteed users in real time, prompting power supply risks, and effectively ensuring the reliability of power supply.
Description
technical field [0001] The invention belongs to the field of electric power system scheduling automation, and in particular relates to a risk analysis method for hierarchical operation of guaranteed power supply areas based on the integration of master and distribution. Background technique [0002] The traditional important user operation status monitoring only realizes the monitoring of the power supply on the distribution network side of the user. Due to the lack of main network path information, it is impossible to monitor the power supply status of the main network power supply, and it is impossible to provide important users with transmission and distribution integrated high reliability operation risk analysis and warning. Based on the integrated system architecture of the transmission and distribution network, the operation risk assessment and early warning of the entire transmission and distribution path of important users (power maintenance users) can be realized.
