Problems solved by technology

[0003] Without the substation, the grid power supply area will be in darkness, without the station-side DC power system, the substation will be completely paralyzed; at present, because the data and status information of the low-voltage power supply system of the substation cannot be completely collected, only the faults that have occurred in the system can be reflected Due to the situation, it is impossible to grasp the changing trend of the operating status of the low-voltage power supply system equipment, let alone the ability to analyze and process the operating information of the substation power system and to evaluate the online status, and it is impossible to guide the operation and maintenance department to carry out targeted maintenance work in a timely manner to effectively protect the substation power system. safe and stable operation of

Abstract

The invention discloses an online state evaluation system and method for a substation power supply. The system comprises a substation power supply system information acquisition subsystem of a transformer substation end and a power supply system online state evaluation main system of a dispatching end. The subsystems realize the construction of an equipment model of the substation power supply system for the substation end station and the collection and uploading of operation information. The main system of the dispatching end uses a substation end power supply system model and real-time operation information uploaded by the subsystem. Depending on an on-line state evaluation strategy of the substation power supply system, the system achieves the online monitoring of the operation state ofthe substation power supply system for the substation end and the online state evaluation of the operation condition of the system, achieves the online monitoring and evaluation of the power supply system for the role-shaped transformer station oriented to the operation personnel and professional operation and maintenance personnel, and improves the level of safe operation and risk early warningof the transformer station.

Description

technical field [0001] The invention belongs to the technical field of electric power system dispatching automation, and in particular relates to an online state evaluation system and method for a substation power supply. Background technique [0002] There are many problems in the operation and maintenance process of the substation. Among them, the substation power supply system is an important link to ensure the safe and reliable operation of the substation. It is mainly composed of three parts: the station AC power system, the DC power system and the AC uninterruptible power supply system. composition. The DC system of the substation is the most important system for supplying power to the self-owned equipment in the substation. Its main loads are power supply for protection, measurement and control and other automatic devices, power supply for control loop, power supply for operation loop and emergency lighting, etc. The main components of the DC system of the substation...
