Problems solved by technology

However, considering uncertain factors such as bad weather, equipment failure, and misoperation during the execution of the operation, the scheduling operation may not be performed normally, which will affect the safe and stable operation of the system.
[0003] At present, the research on dispatching operation mainly focuses on deterministic safety calibration, and prevents misoperation by monitoring all aspects of dispatching operation; however, there is no technology that can detect the risks brought by dispatching operation to the system

Embodiment Construction

[0027] The present invention proposes a risk detection method for grid dispatching operation, and its implementation flow chart is as follows: figure 1 , including steps:

[0028] S1. Receive the current operation instruction performed on the destination device, and determine the risk status information of the current operation performed on the destination device;

[0029] Wherein, the risk status information includes: the risk status information of the current operation of the target device, the operation success development status information of the target device, and the historical statistical status information of the target device when the operation fails;

[0030] The risk of dispatching operation to the power grid mainly comes from the following three aspects: First, the risk of operation failure caused by the failure of the component itself, that is: the historical statistical state information of the destination equipment when the operation fails, such as the process ...

Abstract

The invention provides a risk test method for power gird dispatching operation. The risk test method for the power gird dispatching operation comprises the steps: receiving a current operation command conducted to target equipment and confirming risk state information; obtaining the number of nodes which are beyond a voltage boundary, overload number of branches, actual voltage amplitude value of each node which is beyond the voltage boundary and actual transmitting power of each overload branch under the states of failed operation, successful operation and successful operation development; obtaining load reduction quantity after failure and load reduction quantity under successful operation; obtaining real-time probabilities when operation succeeds and fails; obtaining real-time probability of failure after operation fails and real-time failure probability of the target equipment when operation succeeds; obtaining a risk indicator of the current operation; and sending an alarm out when the risk indicator is larger than or equal to a preset value. The invention further provides a risk test device for the power gird dispatching operation. The risk test device for the power gird dispatching operation is capable of pre-testing security status of a power gird caused by the power gird dispatching operation and guaranteeing the safe operation of an electrical power system.

Description

technical field [0001] The invention relates to the field of power grid dispatch control, in particular to a risk detection method and device for power grid dispatch operation. Background technique [0002] In order to ensure the safe, economical and reliable operation of the power grid, the dispatcher must take reasonable dispatching operations. At present, dispatchers mainly operate the power grid based on the real-time operation data of the power grid and personal experience. The dispatching operation order ticket has a relatively complete set of operation procedures and control methods from the formulation to the final execution, which ensures the safety of power dispatching to a large extent. However, considering the uncertain factors such as bad weather, equipment failure and misoperation during the operation execution, the scheduling operation may not be executed normally, affecting the safe and stable operation of the system. [0003] At present, the research on di...
