Substation balance monitoring system

Abstract

The invention provides a substation balance monitoring system, which comprises a manual setting non-calculation module, a calculation basis judgment module, an unbalance rate calculation module and anabnormal condition number-setting module, and is characterized in that the calculation basis judgment module respectively performs grid model building, file integrity judgment, acquisition conditionjudgment and original number condition judgment; the unbalance rate calculation module calculates the bus unbalance rate, the transformer unbalance rate and the line unbalance rate respectively; the abnormal condition number-setting module directly sets the corresponding unbalance rate to be 100% when certain measurement is judged to be an acquisition abnormity or original number abnormity. The substation balance monitoring system finally gives a substation balance rate index through unbalance rate calculation, balance judgment and balance station judgment, the substation electric quantity balance monitoring standard is standardized, and a unified index system, which meets same-period line loss requirements and can guide specialized and collaborative management of the power grid, is established.

Description

technical field [0001] The invention belongs to the technical field of substation monitoring, in particular to a substation balance monitoring system.

AI Technical Summary

Problems solved by technology

However, based on the electric energy collection system, there are no relevant research reports on large-scale and comprehensive substation electric energy balance monitoring research and system function construction, which are used to fully support the construction of the national grid's line loss during the same period.

[0003] At present, there is no unified standard method for the calculation of electric energy balance indicators. It is necessary to comprehensively consider the existing electric energy collection technical support level, the line loss requirements of the same period, and the professional management needs of the power grid, etc., to study the optimal calculation scheme, including the selection of the time window for power calculation, Metering point electric energy substitution method, abnormal electric energy replacement method, computing resource requirements, metering point state management, etc.
