What are the problems in the safety management of power plants at present?

Habitual violation refers to long-term violation of the rules and regulations that cannot be changed in the short term, such as "Electric Power Safety Work Regulations".

Because habitual violation of regulations does not necessarily lead to safety accidents, it will lead to poor safety awareness of a large number of staff.

In specific work, staff often show that they can't consciously abide by the rules and strictly implement the work rules, thus increasing the frequency of habitual violations.

A large number of data show that in recent years, more than 90% of accidents caused by unit safety accidents in thermal power plants in China are related to violations, and the proportion of habitual violations is as high as 78%.

(B) analysis of dangerous points is not in place

Dangerous point refers to the place, position and place where accidents are prone to occur during the operation.

In specific work, due to the low safety awareness of some staff, it is impossible to effectively control the whole operation process through hazard point analysis, and then safety accidents occur.

Because of the long-term emphasis on safety management assessment, it is impossible to improve employees' safety awareness from the aspects of thoughts, attitudes and values, and then it is impossible to fundamentally solve the potential safety hazards and prohibit the occurrence of safety accidents.

(C) the lack of safety supervision agencies

At present, many thermal power plants have not established effective safety supervision institutions. Even if the safety production committee is established, it is only at the enterprise level, and it has not been implemented in every production link, workshop and employee.

Extended data:

Electric power operation standard:

1, normal start-stop and line switch operation standardization, normal start-stop and high line switch operation frequency. The power plant has formulated a standard and unified typical operation ticket for the normal start-stop, shutdown and power transmission of the unit, and improved and refined it, thus standardizing the operation standard and shortening the operation time.

After receiving the operation ticket, the operator can complete the filling and review of the operation ticket in a short time after checking the operation ticket and equipment, and then operate one by one according to the steps on the operation ticket. The operation ticket is only authorized to the shift supervisor.

2. Bus switching operation is standardized. There are many devices related to bus switching operation, and the power flow mode of the system is considered more. It is difficult to make a unified typical operation ticket.

Therefore, according to the long-term operation experience and the operation requirements in actual operation, the power plant has formulated the implementation standard suitable for bus switching operation.

1 10kV and above busbar switching operations are mostly predictive switching operations. According to its specific requirements, the detailed operation plan is formulated in advance, the complete switching operation ticket is prepared, the operators are arranged reasonably, and the accident prediction of switching operation is made well, which not only ensures the operation quality, but also does not delay the operation time.

For switching operation of auxiliary power system below 1 10kV, standard switching operation procedures and corresponding operation tickets can be compiled according to possible states and operation items of auxiliary power system, and integrated into the operation ticket execution system of power plant management information system (MIS).

This can effectively avoid threatening the safe operation of the unit due to the loss of power of important auxiliary equipment during the switching operation of the auxiliary power system.

In order to ensure the equipment and personal safety of new and old units in the process of isolation, exit, maintenance and recovery, according to the "Electric Power Safety Work Regulations" and the actual configuration of equipment and personnel, the duty mode with relatively independent operation and duty is adopted.

That is, the operation is separated from the duty work, and the switching operation is completed by special operators, thus realizing the transformation to the "unattended" (less attended) operation duty mode.
