Description

A power dispatching operation method and system thereof

technical field

The invention relates to the technical field of power dispatching, and in particular to a power dispatching operation method.

Background technique

In the safe operation of the power grid, the correct operation of the power grid is a very important task to ensure the safe operation of the power grid. Electrical misoperation may cause large-scale power outages, equipment damage, personal casualties, and even cause serious consequences such as grid oscillation and collapse. The correct preparation, review and execution of the operation ticket is a powerful guarantee to prevent misoperation. Therefore, the three-trial system is introduced before the operation of the grid dispatching operation ticket. The third review of operation tickets is often reviewed by dispatchers in different positions with years of experience, and there is a lack of system dimension checking.

As the power grid structure becomes more and more complex, the planned maintenance work and signal monitoring of power grid equipment are increasing day by day, and the workload and risks borne by power dispatchers are increasing. When the dispatcher performs various planned work, defects and accident handling, he can only rely on manual review of operating conditions, and there are errors in evaluating the power flow of the system and the loss of voltage at the plant, which leads to misoperation of power dispatching. In order to prevent all kinds of mis-scheduling, mis-remote control and mis-operation, and identify and deal with faults in a timely and accurate manner, the expert reasoning mechanism is introduced, and safety checks are carried out in the whole process of control and operation, so that the scheduling and monitoring work is more orderly, safe, and reliable. Efficient, and further promote the development of the integrated control model to the direction of intelligence.

In various dispatching operation events, after the adjustment of the busbar mode (ie, the inverted busbar), due to the complex structure of the power grid and the negligence of personnel review, some interval operations are not in place, which may easily cause power loss of lines and plants, resulting in loss of voltage. To prevent errors in the conventional system topology, it is necessary to refine the operation order of each step into an operation sequence before it can be checked. In actual operation, if the operation of the inverted bus is to refine each interval operation sequence, one is too cumbersome and takes up a lot of work, the other is error-prone, and the third is that the operation of the inverted bus is mainly on-site in the actual scheduling work, and the safety responsibility is on the spot.

In this embodiment, when the power grid operation monitoring system fails the rehearsal check of the current operation order, the power dispatching operation is interrupted, and a prompt message that the rehearsal check of the current operation order fails is output.

In this embodiment, the dispatching command and control system obtains the operation result information uploaded by the operator, performs system status checking according to the operation result information, and sends the operation result information to the power grid operation monitoring system for system status checking. nucleus, including:

The dispatching command and control system obtains the operation result information about the current operation order uploaded by the operator, checks the system state according to the operation result information, and generates a DCCS system state about the current operation order when the system state check passes. Check the passed information;

The dispatching command and control system sends the operation result information to the power grid operation monitoring system according to the operation result information;

The power grid operation monitoring system performs a system state check according to the operation result information, and generates an OCS system state check pass information about the current operation order when the system state check passes, and sends the OCS system state check pass information Sent to the dispatch command and control system.

In this embodiment, determining whether the operation is successful according to the system state check results of the dispatching command and control system and the power grid operation monitoring system, and when determining whether the operation is successful, determines whether to enter the power dispatching operation of the next operation order, including: :

When the dispatching command and control system obtains the DCCS system status check pass information and the OCS system status check pass information, the dispatch command and control system determines whether the current operation order is the last operation in the third-trial operation ticket information order; if it is the last operation order, end the power dispatching operation; if it is not the last operation order, enter the power dispatching operation of the next operation order.

In this embodiment, the third-trial operation ticket specifically includes an inverted bus operation order for performing a setting operation according to the final target mode.

Specifically, take the wiring method as shown in Figure 3 as an example: I run with the B line and D line; II run with the A line, C line, and E line. The operation mode needs to be adjusted as follows: I mother hanging line A, C line, E line operation; II mother hanging line B, D line operation.

According to the conventional check logic, the following sequence of operations needs to be sent to the check system:

①A wire closes the 1011 knife switch and opens the 1012 knife switch;

② Line B closes the 1022 knife switch and opens the 1021 knife switch;

③Close the 1031 knife switch on the C line and open the 1032 knife switch;

④Close the 1042 knife switch on the D line and open the 1041 knife switch;

⑤ Close the 1051 knife switch on the fifth line, and open the 1052 knife switch;

Need to go through the above 5 steps, 10 pull together to complete.

This method requires the dispatcher to decompose an inverted bus operation order into 10 actions to complete, the action analysis process is complex, the implementation is difficult, and errors are prone to occur in manual decomposition of the order.

In order to solve this problem, the present invention proposes checking based on the strong setting method. That is, according to the operation order "I mother hangs A line, C line, E line operation; II mother hangs B line, D line operation", it is directly parsed as:

"I mother: Line A 1011 knife switch closed position, 1012 knife gate split position; C line 1031 knife gate closed position, 1032 knife gate split position; E line 1051 knife gate closed position, 1052 knife gate split position";

"II mother: B line 1022 knife switch closed position, 1021 knife switch position; D line 1042 knife switch closed position, 1041 knife switch position";

Ignore the opening and closing action of the intermediate knife switch, and directly perform the setting operation according to the final target method, which is in line with the actual scheduling work and reduces the verification steps and analysis risks.

In this embodiment, for the complicated check of the inverted bus, from the perspective of dispatching the actual business, the bus is strongly set, and the method of hanging the line after the setting is used as the basis, and the check is carried out for the subsequent operations.

Based on the above embodiment, it can be seen that this embodiment is based on heterologous verification. After the operation is completed by the on-site operator, the DCCS system returns the order, and the DCCS automatically receives the order and checks it. At the same time, it is compared with the check result of the OCS system. After the system verification is passed, the next step operation order is automatically issued. If there is no abnormal situation, the system will automatically order and receive the order. This process does not require manual intervention, which greatly improves the operation efficiency. If one or two sets of systems fail to pass the check, it will be interrupted and an alarm will be issued, and the dispatcher will manually intervene and deal with it. Thereby avoiding the risk of human omission and improving operational efficiency and operational reliability.
