Method and device for bringing terminal plant station measurement data into DTS simulation calculation

Abstract

The invention discloses a method and a device for bringing terminal plant station measurement data into DTS simulation calculation. The method comprises the following steps: obtaining plant station information read in an SCADA library, and screening out a target terminal plant station which is excluded by PAS and needs to be brought into DTS simulation calculation; obtaining model information anda topological relation of the target terminal plant station from the SCADA library; carrying out load initial value distribution on the target terminal plant station according to the model informationand the topological relation; and taking the load initial value distributed to the target terminal plant station as a power flow initial value of DTS simulation calculation and bringing the load flowinitial value into DTS simulation calculation. According to the invention, the measurement data of an excluded terminal plant station can be brought into DTS simulation calculation, and the simulation operation of a DTS on the terminal plant station is realized.

Description

technical field [0001] The invention relates to a method and a device for incorporating measurement data of a terminal station into DTS simulation calculation, and belongs to the technical field of power system simulation training. Background technique [0002] In order to effectively support the construction of the "big operation" system, the Beijing Electric Power Control Center has carried out the transformation of the dispatching technical support system for the transformation of the integrated operation mode of regulation, and developed and constructed the smart grid dispatching control system (D5000). The expansion of responsibilities and the expansion of business scope have put forward high requirements for the grid operation skills of the city and district power grid regulation operators. The controller training simulation modern system tool (DTS) of the intelligent dispatching control system platform can fully support the training business needs of the Beijing Munic...

AI Technical Summary

Problems solved by technology

[0007] (1) The maintenance efficiency is low. The stations excluded by state estimation need to be checked manually. There are a large number of dispatched stations in Beijing, and there are many types of stations. The efficiency of manual search for terminal stations excluded by PAS is very low. The method relies heavily on the configuration file, the configuration file needs to be manually filled, uploaded and verified, the maintenance cycle is long, and the efficiency is low

[0008] (2) The error tolerance rate is low. There are many contents to be filled in a single line of the configuration file, and no missing or wrong filling is allowed. The interval between columns is strictly required, and the coding method is also required. If there is a single unsatisfactory situation, the factory station cannot Successfully joined the calculation

[0009] (3) The calculation efficiency is poor. After the existing method reads the corresponding plant information through the configuration file, it needs to traverse and match the equipment information storage file, and the calculation efficiency of the program reading data is low.

[0010] (4) The power flow convergence is poor. The equipment status of the actual production system is constantly changing. The status of the excluded plants is not refreshed in the PAS database. The remote signal information of the switch is not accurate, and the power flow calculation is not easy to converge.
