Embodiment Construction

[0037] A non-limiting embodiment will be given below in conjunction with the accompanying drawings to further illustrate the present invention. Obviously, the described embodiment is only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] The power grid operation mode is the overall technical plan for the production and operation of the power system compiled by the power system dispatching department. Various simulation calculations are required when the operation mode is compiled, and the safety and economy of the operation mode are checked through the simulation calculation results.

[0039] In order to enable the intuitive three-dimensional display of the operation mode calculation results on the sand table independently of t...

Abstract

The invention discloses a method and a system thereof for dynamically displaying a power grid simulating calculation result through a sand table, and relates to a power grid simulation method and a system of the power grid simulation method. At present, power grid operation mode personnel mainly adopt off-line simulation software to carry out power grid security stability calculation, but a result can not be intuitively displayed. The method comprises the following steps: setting power grid sand table displaying scene parameters, an operation mode, a calculation type and an anticipatory fault set; carrying out anticipatory fault calculation by aiming at the anticipatory fault set, mapping a calculation result into a power grid simulation model; furthermore, converting the power grid simulation model into a dynamic model and a control model used for sand table display; and finally, outputting the dynamic model to the power grid sand table. The technical scheme solves a relevant technical problem that the power grid simulating calculation result can not be independently and dynamically displayed through a three-dimensional sand table, the power grid simulating calculation result is dynamically displayed by a sand table technology, and third dimension and intuition are high.

Description

technical field [0001] The invention belongs to the field of power grid simulation, and in particular relates to a sand table dynamic display method and system for power grid simulation calculation results. Background technique [0002] At present, the grid operation mode personnel mainly use off-line simulation software to calculate the grid security and stability, such as BPA (Bonneville Power Administration), PSS / E (Power System Simulator / Engineering) and other simulation software, these simulation software have their own characteristics ;Operation mode personnel often need to switch between multiple simulation software when performing mode calculations. For example, BPA is used to calculate power flow, and PSS / E is used to calculate short circuit. The efficiency is relatively low; and the calculation results are highly coupled with the simulation software itself. The text and power flow graph display is not intuitive. For those who are not familiar with the power grid ...
