Problems solved by technology

[0003] However, due to the large amount of control information that the grid dispatching controllers need to pay attention to, and these control information are often displayed in digital ways, this increases the workload of the grid dispatching controllers. It is beneficial for power grid dispatching and operation personnel to grasp the operating margin status of the power grid in real time and intuitively and make corresponding response judgments in a timely manner

Embodiment 1

[0032] see figure 1 As shown in FIG. 2 , it is a schematic flowchart of the method for displaying the operating margin of the power grid according to the embodiment of the present invention. Such as figure 1 As shown, the grid operation margin display method in this embodiment includes the following steps:

[0033] Step S101: Determine the margin of each load node in the power grid system at the current time and the time determined according to the preset interval thereafter, and enter step S102, wherein the preset interval can be selected according to the actual situation, such as taking 1 hour as the time interval, according to the preset interval The time determined by the interval generally includes multiple times. For example, each time within 24 hours of the current time is determined at an interval of 1 hour. In addition, the margins of each load node at the current time can be determined according to the load nodes in the current power grid system. The load informati...

Embodiment 2

[0048] According to the grid operation margin display method of the present invention, the present invention also provides a grid operation margin display system, and a specific example of the grid operation margin display system of the present invention will be described in detail below. Figure 4 shows a schematic structural diagram of a power grid operation margin display system according to an embodiment of the present invention. In this embodiment, the power grid operation margin display system of the present invention includes a margin determination module 201, a margin division module 202, and a display module 203, of which:

[0049] The margin determination module 201 is used to determine the margin of each load node in the power grid system at the current moment and at the moment determined according to the preset interval, wherein the preset interval can be selected according to the actual situation, such as taking 1 hour as the time interval, according to The time d...

Abstract

The invention provides a method and a system for displaying operation allowances of a power grid. The method includes steps of determining allowances of current time of different load nodes in a power grid system and later time determined according to preset intervals; dividing states of operation allowances of different times of the different load nodes according to allowances of different times of the different load nodes respectively; and displaying the states of the operation allowances of the different times of the different load nodes of the power grid according to corresponding relations between the states and colors of the preset operation allowances. By the method and the system, power grid dispatching operators can control the states of the operation allowances of the power grid in real time visually and conveniently, and accordingly can make corresponding judgments in time.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a method and a system for displaying an operating margin of a power grid. Background technique [0002] With the rapid development of large-scale computing systems, the computing power of mainstream computing platforms has been greatly developed, and the computing power of personal workstations has been able to achieve T times of double-precision floating-point calculations per second in the field of parallel computing. ability. Therefore, many applications that were limited by the bottleneck of computing capacity in the past have gradually entered the stage of practical application. On the other hand, with the gradual acceleration of the construction of smart grids, grid dispatchers need to grasp various real-time operations of the grid more comprehensively and quickly. Information and make corresponding scheduling control plan. [0003] However, due to the large amount...
