Description

Technical Field

[0001] The present invention relates to the technical field of power grid operation control, and in particular to a power grid operation risk control method, device, equipment and storage medium. Background Art

[0002] Operation risk assessment and control is a core component of the safety production risk management system and an important support for ensuring operation safety. Since October 2007, China Southern Power Grid has established a long-term mechanism for operation risk assessment and control, and has formulated a unified operation risk assessment method. Each work team must conduct an operation risk assessment in advance before each operation task begins, and take corresponding control measures based on the operation risk assessment results, so as to effectively prevent operation risks.

[0003] Since power grid operation tasks involve a wide variety of types, the types of risks involved in the operation tasks are varied. For example, a power supply bureau's risk assessment results for the "500kV oil-immersed power transformer preventive test" operation task include but are not limited to the following 10 types of risks: electric shock, blow, local power outage, sprain, equipment damage, equipment burns, equipment fatigue damage, tripping, falling, and power supply with a grounding knife or grounding wire.

[0004] At the same time, it is necessary to evaluate and determine the values ​​of multiple parameters such as consequences, exposure, possibility, etc. of each "risk type" of operational risk in turn before calculating the baseline value of the corresponding risk. In practice, the evaluation of multiple parameters such as consequences, exposure, possibility, etc. involves many types of work, a large number of people, and uneven personnel quality. For the same type of "risk type", different consequences, exposures, possibilities (values) are often evaluated, and the calculated risk values ​​are inconsistent. For the same type of operational risk type, it is often difficult to obtain a unified operational risk value, resulting in the inability to take effective control measures according to the degree of priority, and it is difficult to avoid the weakening of control priorities and the waste of resource distribution, which will be detrimental to the effective control of operational risks. Summary of the invention

[0005] The present invention provides a power grid operation risk management method, device, equipment and storage medium to solve the technical problem that it is often difficult to obtain a unified operation risk value for the same type of operation risk, resulting in the inability to take effective management and control measures according to the degree of urgency.

[0045] Embodiment 1

[0046] Please refer to Figure 1 , is a flow chart of a method for risk management and control of power grid operations provided by an embodiment of the present invention, comprising the following specific steps:

[0047] S1. Obtain the operation risk values ​​of all current operation tasks, and sort the operation risk values ​​of each operation task in descending order;

[0048] The generation of the risk value includes:

[0049] Obtaining the operational risk assessment data of all operators; wherein the operational risk assessment data includes: the name of the operational task, operational hazards, risk type, risk consequence, risk exposure and risk possibility corresponding to each operational task;

[0050] For the same operation task, the risk consequences in the operation assessment data are averaged to obtain the corresponding risk consequence mean, the risk exposure in the operation assessment data is averaged to obtain the corresponding risk exposure mean, the risk possibility in the operation assessment data is averaged to obtain the corresponding risk possibility mean, and the risk value corresponding to the operation task is calculated based on the risk consequence mean, risk exposure mean and risk possibility mean.

[0051] Preferably, it also includes: obtaining the risk level corresponding to each work task according to the risk value of each work task and the preset risk level division range; wherein the risk level includes: acceptable risk level, low risk level, medium risk level, high risk level and extremely high risk level.

[0052] Specifically, the present invention provides an operation risk management method. Aiming at the problem that the operation risk values ​​and risk levels assessed by various power supply bureaus for the same type of operation risk are inconsistent, which is not conducive to the effective management and control of operation risks, firstly, the risk consequences, risk exposure, risk possibility and other data that affect the risk level results are optimized and integrated into coordinated and unified values; then, the risk values ​​and risk levels of "similar risk types in similar operation tasks" of various power supply bureaus are coordinated and unified, and the management and control measures of each risk type are associated; finally, when performing operations, the risk values ​​of the current operation tasks are matched and sorted, and the operation tasks with higher risk values ​​are selected to match the management and control schemes of the corresponding risk types, so as to achieve effective management and control of operation risks, which specifically includes the following steps:

[0053] 1. Generation of Risk Value

[0054] 1. Obtain the operational risk assessment data of all operators:

[0055] Since October 2007, China Southern Power Grid has been promoting and applying the operation risk management system. The operation tasks involved are of various types and have accumulated a large amount of operation risk assessment data. These data are based on the operation risk management system. The operators conduct risk assessments on each operation task based on their subjective cognition, assess the risk level, and select risk control measures for management and control. Among them, the operation risk assessment data of similar operation tasks within the same team are integrated and consistent; moreover, some power supply bureaus also integrate and make consistent the operation risk assessment data. Among them, these operation risk assessment data are basically directly output by the human brain based on the subjective cognition of the operators, and everyone's assessment results are different.

[0056] For example, in the test type of substation, "500kV oil-immersed power transformer preventive test" is a common operation task, and the parameters involved in its risk assessment data are mainly: operation task, hazard name, risk type, risk consequence, risk exposure, risk possibility, risk value, risk level, "recommended control measures", etc. The single parameter of "risk type" includes (but not limited to): electric shock, blow, partial power outage, sprain, equipment damage, equipment burn, equipment fatigue damage, trip, fall, power supply with grounding knife or grounding wire, etc. The risk values ​​of these "risk types" are all obtained by the operators based on subjective cognitive assessment. The assessment work involves many people and is complicated, resulting in inconsistent risk assessment results for the same "risk type". Please refer to the following Table 1, taking the operation task of "500kV oil-immersed power transformer preventive test" as an example for data display, where risk value = consequence × exposure × possibility.

[0057]

[0058] Table 1 Risk data of 500kV oil-fired transformer pre-test operation

[0059] 2. Use the mean calculation method to assess the risk value of the operation

[0060] In view of the large discreteness of the risk values ​​assessed for the same risk type in the above-mentioned risk assessment data, an "average" algorithm is adopted for optimization and integration. For the same work task, the risk consequences in the work assessment data are averaged to obtain the corresponding risk consequence average, the risk exposure in the work assessment data is averaged to obtain the corresponding risk exposure average, the risk possibility in the work assessment data is averaged to obtain the corresponding risk possibility average, and the risk value corresponding to the work task is calculated based on the risk consequence average, the risk exposure average and the risk possibility average, so that they are basically coordinated and unified, and a relatively unified risk value is obtained, thereby eliminating the inconsistency problem caused by the large number of work risk assessors and their uneven quality, and thereby improving the coordination of risk control measures for similar work tasks and the effectiveness of on-site work risk control.

[0061] For example, the geometric mean calculation method is used to calculate the risk data of the 500kV oil-fired transformer pre-test operation in Table 1:

[0062]

[0063] Similarly, we can get:

[0064]

[0065] so:

[0066] Similarly, using the same mean calculation method, other "risk types" in the task (strike, local power outage, sprain, equipment damage, equipment burn, equipment fatigue damage, tripping, falling, power supply with grounding knife or grounding wire, etc.) can be calculated to obtain relatively uniform risk values ​​for other "risk types".

[0067] Please refer to Table 2 for the mean calculation results of the risk data of the 500kV oil-fired transformer pre-test operation.

[0068]

[0069] Table 2 Mean calculation results of 500kV oil-fired transformer pre-test operation risk data

[0070] In addition, the risk level corresponding to each operation task can be obtained according to the risk value of each operation task and the preset risk level classification range; wherein the risk level includes: acceptable risk level, low risk level, medium risk level, high risk level and extremely high risk level. In a specific embodiment, please refer to the following Table 3 for the classification range of operation risk levels.

[0071]

[0072] Table 3 Scope of classification of operation risk levels

[0073] II. Operational Risk Control

[0074] 1. Risk value acquisition:

[0075] After calculating a unified risk value and risk level for each operation task, the risk value and risk level are associated with the corresponding operation task and stored in a database. Then, before performing on-site operations, the operation risk values ​​of all current operation tasks are first obtained from the database, and the operation risk values ​​of each operation task are sorted in descending order.

[0076] S2. Obtain the current number of controllable tasks, and select the same number of tasks as the controllable tasks as target tasks in descending order of the operation risk value of each operation task;

[0077] 2. Task selection:

[0078] Each risk type of work task has a unified risk value. The system automatically sorts them according to the size of the risk value, and then selects the part of work tasks starting with the highest risk value from these risk value lists as target work tasks for control. The number of controllable tasks can be obtained based on the actual control requirements of the work site (such as the workload of 2-person control or 4-person control).

[0079] S3, matching the operation risk control plan corresponding to each target operation task according to the risk type of each target operation task, and then performing risk control on each target operation task according to the operation risk control plan;

[0080] Preferably, the risk types include: electric shock, falling, power supply with grounding wire and poisoning in confined space; according to the operation risk control plan, risk control is performed on each target operation task, including: according to the operation risk control plan, anti-electric shock control is performed on the target operation task with the risk type of electric shock, anti-falling control is performed on the target operation task with the risk type of falling, anti-power supply with grounding wire is performed on the target operation task with the risk type of power supply with grounding wire, and gas content detection control is performed on the target operation task with the risk type of poisoning in confined space.

[0081] Preferably, the anti-electric shock control for the target work task with the risk type of electric shock includes: for the target work task with the risk type of electric shock, obtaining the voltage signal of the three-phase wire at the work site through a preset voltage sensor probe, judging whether the three-phase wire is energized according to the voltage signal, and generating a corresponding alarm signal when it is determined that the three-phase wire is energized.

[0082] Preferably, the anti-fall control for target work tasks with a risk type of falling includes: for target work tasks with a risk type of falling, performing safety checks on the safety belts of workers at the work site, determining whether the hooks on the safety belts are in an effective fastening state, and generating a corresponding alarm signal when it is determined that the hooks on the safety belts are not in an effective fastening state.

[0083] Preferably, the prevention of power transmission with a ground wire is controlled for the target operation task whose risk type is power transmission with a ground wire, including: for the target operation task whose risk type is power transmission with a ground wire, the loop resistance value of the power line at the operation site is detected, and the loop resistance value is compared with a preset threshold value, and when it is detected that the loop resistance value is less than the preset threshold value, a corresponding alarm signal is generated.

[0084] Preferably, the gas content detection and control for the target work task with the risk type of confined space poisoning includes: for the target work task with the risk type of confined space poisoning, the gas concentration of the harmful gas in the confined space of the work site is detected respectively, and the detected gas concentration is compared with a preset gas concentration threshold, and when the gas concentration is greater than the gas concentration threshold, a corresponding alarm signal is generated.

[0085] 3. Operational risk management and control plan matching:

[0086] According to the risk type of each target operation task, the operation risk management plan corresponding to each target operation task is matched, and then the risk of each target operation task is controlled according to the operation risk management plan.

[0087] In a specific embodiment, the risk types include electric shock, falling, power transmission with grounding wires, and poisoning in confined spaces. The operation risk control schemes corresponding to these risk types are as follows:

[0088] (1) Conduct anti-electric shock control for target operations with risk types of electric shock, detect nearby live conditions, and issue relevant warning signals. First, install the electric test device on the high-voltage conductor part of the operating equipment. The card reader can wirelessly read whether the high-voltage conductor part is live to guide the anti-electric shock work during the operation. Specifically, by arranging three "source-sensing integrated" voltage sensor probes, the voltage signals of the three phases A, B, and C can be collected at any time, and the collected results can be analyzed and calculated to determine whether the (three-phase) conductor is live, thereby effectively avoiding the situation where the single-phase voltage passes through zero or near zero (lower than the "live threshold") and causes misjudgment, and realizes the full-condition, non-contact, and effective voltage collection (electricity test) of the conductor with passive collection and passive wireless transmission, further preventing personal electric shock and ensuring personal safety.

[0089] (2) Carry out fall prevention control for target work tasks with the risk type of falling, detect whether the safety belt is effectively fastened, and issue relevant warning signals. Carry out safety inspections on the safety belts of workers at the work site, and install an alarm circuit with a grating on the hook of the safety belt. When the hook of the safety belt is effectively fastened, the hook will block the light and no alarm signal will be issued; when there is no hook blocking the light, an alarm signal will be issued. Specifically, a (small and low-energy) photoelectric switch is installed at one end of the hook ring, and a light-absorbing material is coated on the inner wall of the other end of the hook ring to change the boundary conditions. When there is no object in the hook ring, the light directly irradiates the light-absorbing material, and the photoelectric switch cannot detect the reflected light; when there is an object in the hook ring, the light irradiates the object, and the photoelectric switch detects the reflected light.

[0090] (3) For the target operation task with the risk type of power transmission with grounding wire, control is carried out to prevent power transmission with grounding wire, detect whether there are unremoved grounding wires or grounding knives on the line before power transmission, and issue relevant warning signals. Measure the loop resistance value connecting "line conductor, the last (known) grounding wire and the earth". When the loop resistance value is close to infinity (the loop is open), there are no other unknown grounding wires left on the line, and the device does not issue an alarm signal; when the loop resistance value is less than the preset value (the loop is open or closed), there are other unknown grounding wires left on the line, and the device issues an alarm signal. Specifically, two clamp meters with different measurement frequencies are clamped on any group of grounding wires or the grounding lead of the line grounding knife at the same time, and the total impedance Z1 (measurement result reading of clamp meter 1) and Z2 (measurement result reading of clamp meter 2) of the power line are measured respectively, and the resistance R and reactance X of the line are calculated, and then the influence of reactance X is eliminated, and then the resistance R is effectively detected to sense whether there is a closed loop in the line, so as to accurately judge whether the remaining grounding wires of the power line are removed.

[0091] (4) For target tasks with the risk of poisoning in confined spaces, gas content detection and control are carried out to detect the gas content in the air in confined spaces such as cable tunnels and indoor GIS rooms, and issue relevant alarm signals. A four-in-one gas detector can be used in confined spaces such as cable tunnels and indoor GIS rooms to detect the concentration of oxygen, combustible gas, carbon monoxide, and hydrogen sulfide in the air. When the measured gas reaches the preset alarm, an audible and visual alarm will be automatically issued.
