The embodiment of the invention discloses a computer device applied to power grid risk analysis, which is shown in a figure 1 and comprises the following components:
a memory 11 for storing a computer program;
a processor 12 for implementing the following steps when executing the computer program:
respectively acquiring a first maintenance list at a primary side of power and a second maintenance list at a communication side;

and determining services corresponding to the first risk range, the second risk range, the third risk range and the fourth risk range respectively.
The risk identification in this embodiment includes, but is not limited to: static safety analysis, wherein the scraping fault of the equipment n-1, the simultaneous fault of the parallel operation on the same tower and the like are mainly considered; transient stability, frequency stability, voltage stability, short-circuit current calculation and small interference stability; power and electricity balance, local power grid power supply capacity and the like.
Accordingly, the risk range includes the risk equipment and/or plant station that needs to pay attention when performing the maintenance task on the maintenance sheet, so as to ensure the personal safety of the staff performing the maintenance task, such as electric shock or falling objects, the equipment safety of the power grid system, the operation safety of the power grid system, such as short circuit or power overload of the line, the power utilization safety of the user, such as sudden power failure or insufficient power, and the environmental safety, such as oil leakage or fire.
In the specific risk identification, load flow calculation is carried out by using parameters, operation parameters and the like of each device in the power grid system to obtain operation parameters of each device and station in the power grid system corresponding to the maintenance list, whether the operation parameters exceed the prediction range is further judged, and if the operation parameters exceed the prediction range, the operation parameters are considered to belong to the risk range.
It can be understood that there is a corresponding relationship between the devices on the primary side of power and the devices on the communication side in the power grid system, and the devices on the primary side of power and the devices on the communication side affect each other, and one side of the devices changes and the other side of the devices changes accordingly, so that by using a physical-information flow coupling calculation method, when the risk range of one side is known, the risk range of the other side of the devices that affect each other can be determined, that is, the third risk range of the communication side corresponding to the first risk range of the primary side of power is determined according to the first risk range of the primary side of power, and the fourth risk range of the primary side of power corresponding to the second risk range of the communication side is determined according to the second risk range of the communication side.
Further, the computer apparatus may further include:

Further, the processor 12 is specifically configured to implement the following steps when executing the computer program:
and respectively determining the risk levels and the risk types of the first risk range, the second risk range, the third risk range and the fourth risk range.
It can be understood that the plant and/or the risk equipment corresponding to the risk range should correspond to different risk levels and risk types according to the risk identification result, the risk levels are mainly classified according to the size and severity of the influence range, and the risk types correspond to personal safety when the staff performs the overhaul task, equipment safety of the power grid system, operation safety of the power grid system, power utilization safety of the user, environmental safety and the like.
Correspondingly, the processor 12 is further specifically configured to implement the following steps when executing the computer program:
and differentiating and displaying the risk grades and the risk types of the first risk range, the second risk range, the third risk range and the fourth risk range through the display 13.
It will be appreciated that the display 13 displays the above risk ranges differently depending on the risk level and risk type of the processor 12 to more intuitively and quickly represent the differences between the risk devices and/or plant stations.
Therefore, according to the method, the device on the other side which is affected when the device on one side of the primary power side and the communication side is in risk is determined through a physical-information flow coupling calculation method, and the devices on the two sides which need to be concerned in the risk range are comprehensively obtained without omission, so that the influence of maintenance on the primary power side and the communication side can be rapidly and accurately mastered.
The embodiment of the invention discloses a computer device specifically applied to power grid risk analysis, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme. Specifically, the method comprises the following steps:
the first risk range, the second risk range, the third risk range, and the fourth risk range each include risk devices and/or stations.

and determining the third risk range from the first prediction range and determining the fourth risk range from the second prediction range according to preset equipment parameters.
It can be understood that, although the first prediction range and the first risk range, and the second prediction range and the second risk range have related corresponding relationships, the prediction range on the other side corresponding to the risk range confirmed according to the service order does not necessarily have a larger service risk due to the influence of the risk on the opposite side, for example, the first risk range on the primary side of the power may have a certain risk change, which may cause a change in the equipment or plant station within the first prediction range, but does not necessarily exceed the normal range value obtained according to the preset parameter of the equipment, and if the first risk range value exceeds the normal range value, it is confirmed that the equipment belongs to the third risk range.
Therefore, the process of determining the prediction range and then determining the risk range can reduce the overhaul workload and reduce the workload.
