A management system for power grid of petrochemical enterprises

Abstract

The invention discloses a management system used for the power grid of a petrochemical enterprise. The management system comprises an auxiliary decision module, an enterprise data module, and an equipment operation analysis module, the enterprise data module and the equipment operation analysis module are respectively connected with the auxiliary decision module, the enterprise data module is connected with the equipment operation analysis module in a communication manner, and the auxiliary decision module is used for monitoring the operation state of the power grid according to the data of the enterprise data module and the equipment operation analysis module and uploading the operation state of the power grid to a control center. According to the management system, the safety and reliability and the economic benefit of the power grid can be effectively improved, the probability of great accidents due to unplanned shutdown of a device caused by "electric dazzling" of the power grid is reduced, the management object of optimal power grid overall safety economic and technical index is realized, the safety operation management system of the enterprise power grid and electrical equipment is established so that the safety management level of the power grid is improved, and centralized storage and management of power grid data are realized.

Description

technical field [0001] The invention relates to the technical field of petrochemical electrical safety, in particular to a management system for power grids of petrochemical enterprises. Background technique [0002] At present, the current safe and stable operation level, economic and technical indicators, and information management methods of the power grid of petrochemical enterprises need to be further improved, which is mainly reflected in the following aspects: the continuous expansion and reconstruction of the enterprise power grid, the building block expansion of the main network structure, and the system running close to the limit , the anti-disturbance ability is weak. If any equipment fails or the external power grid fluctuates, it will affect the normal operation of the enterprise power grid to varying degrees, causing the power grid "shock power" accident, resulting in unplanned shutdown of the device, and even a complete shutdown of the enterprise power grid , ...

[0002] At present, the current safe and stable operation level, economic and technical indicators, and information management methods of the power grid of petrochemical enterprises need to be further improved, which is mainly reflected in the following aspects: the continuous expansion and reconstruction of the enterprise power grid, the building block expansion of the main network structure, and the system running close to the limit , the anti-disturbance ability is weak. If any equipment fails or the external power grid fluctuates, it will affect the normal operation of the enterprise power grid to varying degrees, causing the power grid "shock power" accident, resulting in unplanned shutdown of the device, and even a complete shutdown of the enterprise power grid , and even cause major accidents such as fire and explosion

The Maoming Ethylene 6.3 fire accident in 2008 was caused by lightning strikes on the power line, which caused the power system to "shock" and cause unplanned shutdown of the device; the growth rate of the enterprise's development and power load was underestimated. It is difficult for enterprises to accurately grasp the power flow distribution of the power grid under normal operation and accident state, to choose the best operation mode and to formulate effective measures to prevent the power grid from collapsing. Guarantee the safe and reliable operation of the power system and obtain the greatest economic benefits; unbalanced load distribution, low load rates of distribution transformers and motors, resulting in large power grid losses and low economic operation levels; corporate grid data has not been managed in a unified manner, and a large number of The data are scattered in dispatching, relay protection, operation and other departments for independent management and application, and most of the required information is stored in the form of various written documents and archives, which is not convenient for query, and cannot be updated and maintained in time. At the same time, these power grids There is no uniform specification for parameters in storage format and organization, which brings difficulties to enterprise security supervision
