A remote monitoring system for a power supply system

Abstract

The invention provides a power supply system remote monitoring system. A transformer equipment data acquisition module acquires the analog quantity of field transformer equipment and the current, voltage, active power, reactive power, coil temperature and oil temperature at each side of the transformer. A power supply circuit data acquisition module acquires the current, active power and reactive power of a power supply line, the voltage and frequency of a bus, and the three-phase voltage, three-phase current, zero-sequence voltage and zero-sequence current of the power supply line. A circuit breaker data acquisition module, an isolating switch data acquisition module and a grounding switch data acquisition module are respectively used for acquiring the switching quantity of the field equipment. Through a monitoring platform, systematic data storage is performed, monitoring clients can be connected to share data information, and grid maintenance personnel can exchange knowledge and accumulate data. Typical cases are formed based on stored maintenance process logs, maintenance process cases and related standard or specification files. Related standards, specification documents and operation procedures are provided. Knowledge and experience sharing and management are realized.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a remote monitoring system for a power supply system. Background technique [0002] The distribution network is at the end of the power system, and has the distinctive characteristics of wide geographical distribution, large-scale power grid, various types of equipment, various network connections, and variable operation modes. With the urbanization construction and the growth of electricity demand, the distribution network has been continuously transformed and expanded, and its scale has also been continuously expanded. The scale of most county-level and above distribution networks in the State Grid Corporation system has reached hundreds of feeders. Above, the number of medium voltage feeders in some medium and large cities has reached or exceeded one thousand. [0003] In this way, driven by the development of the national economy, there has been a phenomenon of power cuts; the co...

Problems solved by technology

[0003] In this way, driven by the development of the national economy, there has been a phenomenon of power cuts; the composition of the load has changed, and the residential and commercial power consumption has increased significantly, which has increased the load on some lines and transformers, and even caused partial power outages due to overload; Due to the expansion of local faults caused by the defects of the power system itself, large-scale and long-term power outages occur; because the reactive power supply configuration and adjustment methods do not adapt to the load development, the grid voltage level cannot meet the power quality requirements, resulting in damage to electrical equipment and even occurrence of power failures. Power outage accidents caused by voltage collapse; there are problems with excessive network loss during the operation of the distribution network, etc.
