Nuclear power overhaul work order scheduling management and control method and system

The invention relates to the technical field of nuclear power overhaul, and provides a nuclear power overhaul work order scheduling management and control method, which comprises the following steps of: automatically comparing historical overhaul records through set keywords or IDs, inquiring historical information of work orders, and setting work starting and completion time of the work orders according to a main isolation code window; and in a work execution process, for the work orders with the same main isolation codes, performing management and control operation on the work orders according to the main isolation codes. According to the method, the historical database is combined to analyze which equipment maintenance work orders have the same main isolation codes, the work orders are sorted, the main line plan is combined to schedule the work orders with the same main isolation codes, and the work orders with the same main isolation codes are queried to complete the main isolation codes in the overhaul implementation process. And the work progress is checked and controlled, so that the work efficiency of plan engineers is greatly improved, and the major human error risk that main isolation is removed while work is not completed is avoided.

ActiveCN116127704BNarrow down the selectionReduce capacity wasteCapacitive couplingControl engineering
The application provides a virtual impedance design method and system considering high-precision power output of an inverter, and is suitable for a capacitive coupling inverter. The application firstly selects an equivalent coupling impedance boundary according to a physical impedance calculated active power output limit value; secondly, an inner boundary and an outer boundary meeting instantaneous response requirements are added to reduce the selection range of the virtual impedance; further, a stability margin parameter is introduced to derive a stability boundary of the coupling impedance, further reducing the selection range of the virtual impedance; then, considering possible power loss, a range in which the equivalent impedance approaches zero is taken as a feasible range of the equivalent coupling impedance; finally, a virtual impedance value is obtained by using the difference between the physical impedance and the equivalent coupling impedance. The application can reduce control errors in droop control and reduce capacity waste of CCI.
