Description

A power grid voltage monitoring data platform realizing multi-interface integration

Technical Field

The present invention relates to the technical field of power grid voltage detection, and in particular to a power grid voltage monitoring data platform that realizes multi-interface integration.

Background technique

The qualified rate of power supply voltage is an important indicator for measuring power quality. It directly reflects the network structure, comprehensive management and power supply service level of the power grid. It is an important regulatory indicator of the National Energy Administration for power grid enterprises and a core indicator of the external service commitment of power grid enterprises. With the rapid development of social economy, the load and volatility of the power grid are getting bigger and bigger, the voltage quality problem is becoming more and more prominent, and the complaints about voltage quality are increasing. This has put forward higher requirements for the power supply capacity, voltage regulation capacity and reactive power compensation capacity of power supply enterprises. The National Energy Administration has also launched the full monitoring of voltage quality, requiring the continuous improvement of the voltage quality of the distribution network, the improvement of the monitoring and control capabilities of the distribution network operation, the improvement of power supply reliability, the strengthening of the use of reactive power compensation and regulation capabilities, and the optimization of the reactive power flow of the system to reduce the loss of the entire network, and finally improve the lean management of the distribution network; the comprehensive construction of a modern distribution network with "reasonable structure, advanced technology, flexibility, reliability, economy and efficiency" is the national programmatic requirement for the voltage quality, reactive power control, line loss reduction and reliability improvement of the power system distribution network.

The power grid company's reactive voltage intelligent monitoring and management system was built in 2012 in a district-level two-level mode, realizing the access and application of reactive data from voltage monitors and dispatching automation systems. In 2017, the voltage data from the metering automation system was reconstructed and connected. At present, the system is running stably, but the overall construction plan of the system was designed 10 years ago, and the performance of the hardware equipment can no longer meet the needs of large-scale data access and application; various information systems are gradually adopting a district-level centralized construction model, and the commissioning of the district-level centralized transformation of the metering automation system directly affects the integrity and timeliness of the metering data accessed by the previous reactive voltage monitoring and management system. These current situations have led to the reactive voltage monitoring and management system not being able to effectively support the scientific decision-making of the reactive voltage professional on the planning and construction of the distribution network, and it is urgently necessary to carry out practical transformation of the system.
