Description
Technical Field
The embodiment of the invention relates to the technical field of power grid dispatching anti-misoperation, in particular to an anti-misoperation system for a power grid dispatching end.
Background
With the continuous development and growth of the scale of the power grid, the scheduling operation amount is increased day by day, taking 2018 as an example, the scheduling execution overhaul work of a certain main network in a certain market reaches 4492, 6684 operation instruction tickets are executed, and the complexity and requirements of the operation are also increased continuously. In order to improve the efficiency of command issuing and remote control operation in scheduling, the PCS9000 master station system and the network command issuing system are already established in scheduling. The PCS9000 master station system can be used for manually and remotely operating all switches and part of disconnecting links of a power grid, and has the functions of remote signaling and remote measuring of a full network topology and master network equipment; by deploying the dispatching network command workstation in the transformer substation, the single-track operation of dispatching the network command is realized. However, no matter the dispatcher remotely operates or the network sends out the single-track operation, all need different systems of manual operation to accomplish remote control and order, because of the system lacks the mistake prevention function, the condition of mistake remote control, mistake order down appears very easily, artifical management and control wastes time and energy, and the security is not high to operating efficiency is low, does not satisfy the requirement of regulation and control integration level promotion.
The current situation of the dispatching power-on/power-off operation command flow is analyzed, and two core problems influencing efficiency are obtained: firstly, a dispatcher does not directly control equipment and needs to send a command through a network or communicate with an operation field through a dispatching telephone, so that the time consumption is long, risks exist and the safety is poor; and secondly, the safety error-proof checking means is backward, the state checking is manual, the tide checks the multi-system operation, the waiting time is long, and a worthless link exists. And thirdly, the execution of the dispatching order is divided into a six-step method, wherein after the state of the equipment is manually confirmed by a dispatcher in each step of execution, the order issuing operation is confirmed, the time for the field personnel to wait for the order issuing is long, and the state checking workload before and after the operation of the dispatcher is large.
The programmed operation of the equipment, the sequence control operation of the existing plant station end and the sequence control operation mode have two problems: firstly, the main station programming operation is generally a specific programming control sequence for curing specific lines and equipment, and has strong limitation and a narrow application range; secondly, station-side programmed operation mainly aims at a single station and a single device, cannot be applied to wider devices and multi-terminal cooperation operation, does not have a cross-station comprehensive network topology anti-misoperation function, and is not strong in practicability.
