Embodiment Construction
[0070] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0071] The electronic form-based automatic relay protection setting calculation and verification method of the present invention is based on the power grid equipment and protection devices in the Liaoyuan area of Jilin Province. This method can be modified according to the power grid equipment and protection devices in different regions. Modification, the reference setting calculation program and the setting verification calculation program used by the protection settings of different protection devices can be programmed according to the corresponding setting rules, and the programming methods are similar.
[0072] like figure 1 As shown, the method of the present invention is mainly realized by three modules, namely the basic data maintenance module, the reference fixed value generation module and the protection fixed value verification module, and the bas...

The invention discloses a full automatic relay protection fixed value setting calculation and validation method based on a spreadsheet and relates to the field of power system relay protection. A basic data maintenance module, a reference definite value generation module and a protection definite value validation module are established in the spreadsheet. Calculation programs are fixedly edited in the modules according to a setting calculation principle. Essential data are maintained manually, and the maintained essential data are automatically called to the reference definite value generation module. A plurality of stand-by data are formed according to the setting calculation principle and forms operating data with other data. Then the operating data are calculated by using a reference definite value generation calculation program, and different items of protection reference definite values and protection performance reports are obtained. Relevant items of the protection definite values are automatically called to the protection definite value validation module, and a validation evaluation report is analyzed and output by using a definite value validation calculation program. When the protection fixed values are beyond a set value range, an alert is given. The full automatic relay protection fixed value setting calculation and validation method based on the spreadsheet eliminates error setting and is high in accuracy, small in error and capable of achieving unartificial full automatic setting calculation and validation and maintaining the upgrade automatically.
Description
technical field [0001] The invention relates to the technical field of relay protection of electric power systems, in particular to a method for calculating and verifying the automatic relay protection fixed value setting based on electronic tables. Background technique [0002] At present, the missetting of power system relay protection is mainly reflected in two aspects: calculation management and on-site debugging, and the setting calculation of power system relay protection setting value mainly adopts the following two methods: one is to use calculators, computers and other full manual Calculation, the missetting caused by this method is not unrelated to the data isolation method and the manual calculation process, that is to say, the data required for calculation are independent of each other, and they are used according to the needs of the calculation, and no correlation has been established. Among them, the parameter data management, The processes of formula selection...
