[0002] As the pace of building new power systems accelerates, power systems have been upgraded and reshaped in all aspects such as power generation, transmission, distribution and consumption. This series of changes has brought new challenges to the power quality of power systems. Sensitive equipment and devices widely used in industries such as transportation, smelting and chemical industry, and high-end manufacturing make the product quality of these industries highly dependent on power quality. The decline in power quality may not only cause damage to sensitive equipment, but also cause a large number of products to be scrapped, resulting in serious economic losses. At present, many power quality sensitive users have suffered huge losses due to voltage sag problems, and an effective voltage sag insurance is urgently needed to reduce losses. At present, in the existing research on voltage sag loss insurance, premium calculation relies heavily on the gate statistical data of power grid companies. However, due to the confidentiality requirements of power grid companies for relevant information, insurance companies face huge obstacles in obtaining and using these core data, resulting in a lack of accuracy and reliability in premium calculation. In addition, the main way for sensitive users to deal with voltage sag risks is to simply install governance equipment for compensation. On the one hand, the investment cost of governance equipment is high. On the other hand, there is a lack of organic combination of governance equipment and insurance, and a systematic risk management plan has not been formed. The problems of equipment damage and product scrapping caused by voltage sag have not been effectively solved, and users still face serious risks of economic losses. Summary of the invention

[0019] In the specific implementation of this embodiment, the processor is used to execute the calculation program in the calculation unit, and to input and store user data; the display unit is used to support the user to input and display data.

[0020] Based on the above structure, in the logic of the compensation calculation unit of this embodiment, the user basic data acquisition unit is used to acquire basic data such as the basic structure of the user production line and loss economic data.

Figure 2 The actual voltage sag amplitude U > and duration of sag T < The area is the normal operating area of ​​the equipment, and the voltage sag amplitude is U < and duration of sag T > The area is the equipment fault operation area, and the transition area between the normal operation area and the fault area is the uncertain area. The operation state of sensitive equipment in this area is uncertain, and it may be faulty or normal operation. According to the response mechanism of sensitive equipment to voltage sag, the uncertain area can be divided into three sub-areas (Area A, B and C). Curve 1 is the boundary between the normal operation area and the uncertain area, which is called the upper limit curve; Curve 2 is the boundary between the uncertain area and the fault operation area, which is called the lower limit curve; the two curves correspond to a set of , and , The coordinate value is called the knee point coordinate. Different sensitive devices have different knee point coordinates, which can represent the sensitivity difference of different sensitive devices.

[0022] In the uncertainty areas A, B, and C, the failure probability of the equipment when a temporary sag occurs can be calculated using the following formula:

[0023]

[0024]

[0026] Specifically, the production process of a sensitive user includes multiple sensitive devices. This embodiment further constructs a relationship model between the failure probability of sensitive devices and the interruption probability of the entire production process. In order to simplify the calculation model, this embodiment adopts a combination of series and parallel modules to describe the logical relationship between sensitive devices and industrial production processes. The sensitive devices in the production line are grouped to ensure that the sensitive devices in each sensitive device group are connected in series or in parallel. The failure probability of the device group in the series structure and the failure probability of the device group in the parallel structure are calculated using the following formulas:

[0027]

[0028] Where: is the failure probability of the sensitive equipment group; is the number of series or parallel sensitive devices included in the device group; j is the sensitive device group number. After calculating the failure probability of each device group under a voltage sag event, based on the series and parallel relationship between the device groups, the interruption probability of the entire production process of the sensitive user can be calculated by repeatedly combining the above two formulas.

[0053] According to the insurance level agreed upon by the user and the insurance company, the insurance company needs to compensate the user for part or all of the economic losses caused by voltage sag. The compensation is calculated by the following formula:

[0054] Where: Provide insurance companies with compensation for voltage sag accidents for sensitive users; The annual economic loss of users due to voltage sag calculated according to the insurance level purchased by the users; The number of voltage sag types insured for users.

[0055] The premium rate can be determined based on the insurance expected value principle, which states that the total expected premium of insurance during the claim period should be equal to the insurance company's expectation of compensation for a certain type of risk, that is:

[0056] Where: The first t Annual power quality insurance net premium; The first t Annual power quality insurance compensation.
