The “Administrative Measures for Lightning Protection and Disaster Reduction” of the China Meteorological Administration clearly states: “Meteorological authorities at all levels should strengthen the construction of lightning disaster early warning systems, and improve the lightning disaster early warning and lightning protection and disaster reduction service capabilities.” Research on basic theories such as the occurrence mechanism of lightning and lightning disasters and applied theories such as defense technology, and strengthen the research on lightning protection and disaster mitigation technology and lightning monitoring and early warning systems. According to industry analysts, only about 1/4 of the oil and gas storage enterprises in the country Actively equipped with a lightning monitoring and early warning system, this situation is changing under the mandatory requirements of government departments. The lightning early warning system is expected to become a basic configuration of large oilfield bases. The lightning early warning system based on the measurement principle of the field grinding atmospheric electric field meter makes up for the above shortcomings. The atmospheric electric field at the installation site is continuously sampled by the atmospheric electric field meter to understand the local electric field intensity. When a thunderstorm occurs, the electric field intensity will change sharply. The occurrence of lightning imminent warning. Anhui Jinli Intelligent System has done a good job in lightning monitoring and early warning, lightning online monitoring and protection, etc. It is currently recognized as one of the most effective measures to greatly reduce lightning casualties and disasters.

At any time, Jinli lightning system can detect an approaching thundercloud within 20 kilometers based on changes in the environmental electrostatic field. When the electric field strength of the electrostatic field gradually increases, it means that within the measurement area, the atmospheric electric field detection device can process the data value of the lightning electric field change, analyze the lightning warning level, and wirelessly transmit the data to the early warning through the communication module. Control the host intelligent processing unit, the host intelligently processes GPRS to send the data to the control center, and displays the warning information through the host computer software. The “Administrative Measures for Lightning Protection and Disaster Reduction” of the China Meteorological Administration clearly states: “Meteorological authorities at all levels should strengthen the construction of lightning disaster early warning systems, and improve the lightning disaster early warning and lightning protection and disaster reduction service capabilities.” Research on basic theories such as the occurrence mechanism of lightning and lightning disasters and applied theories such as defense technology, and strengthen the research on lightning protection and disaster mitigation technology and lightning monitoring and early warning systems.

In order to implement the deployment of the "governance plan", on February 24, the Second Division of Hazardous Chemicals Safety Supervision and Administration of the Ministry of Emergency Management compiled the "Large Oil and Gas Storage Base" according to the "Work Plan for Implementing Safety Risk Management and Control Measures for Large Oil and Gas Storage Bases" issued by the State Council Safety Committee Office. Basic Requirements for Lightning Early Warning System (Trial)" and "Basic Requirements for Emergency Shutoff System for Oil and Gas Storage Enterprises (Trial)" to ensure that the equipment and application of large-scale oil and gas storage lightning early warning systems and the rectification of emergency shutdown systems are completed before June 30, 2022. The IEC (International Electrotechnical Commission) standard "Protection against lightning – Thunder storm warning systems, IEC 62793" was finalized in January 2015. The lightning early warning system uses atmospheric electric field detection devices, sensors, etc., and uses the measurement of environmental static electricity. The principle of the field is used to detect and analyze thunderclouds. By collecting lightning-related information in real time, the system realizes real-time monitoring, comprehensive perception, and near-warning of lightning activities in large oil and gas and adjacent areas. The basic functions are as follows: 1. Real-time lightning monitoring, with real-time detection of lightning characteristic parameters such as ground atmospheric electric field. 2. Lightning approach warning, including lightning warning level, lightning warning time, warning area, warning cancellation and other information. 3. Statistical query of lightning historical data, with the functions of lightning early warning information query and statistical analysis in the coverage area. 4. It has the function of data interaction with the national hazardous chemical risk monitoring and early warning platform.

In January 2022, the Work Safety Committee of the State Council pointed out in the "National Centralized Control Plan for Hazardous Chemical Safety Risks" (hereinafter referred to as the "Governance Plan") that "some large oil and gas storage bases such as national oil reserves have a low level of intrinsic safety. Emergency cut-off, gas detection, video surveillance, and lightning warning “four systems” are not perfect”, and there are major safety risks in production and storage。

On the morning of March 17, 2022, Anhui Jinli Electric Technology Co., Ltd. (hereinafter referred to as Jinli Electric), Wang Daoyong, sales manager in central China, and He Ming, head of market support in the technical department, came to PowerChina by appointment. The Smart Energy Company of the Power Design and Research Institute conducted exchanges on new energy lightning protection technology with the leaders and design engineers of the power automation room and other relevant departments. China Power Construction Group Huazhong Electric Power Design and Research Institute Co., Ltd., formerly known as Henan Electric Power Survey and Design Institute, was founded in August 1958 and is affiliated to the world's top 500 enterprises - China Power Construction Group Co., Ltd. It is a national large-scale comprehensive design enterprise with national engineering design comprehensive grade A qualification. With planning and consulting, survey and design, general project contracting, investment and operation as the four main businesses, the business scope involves power transmission and transformation Electricity, new energy, construction, municipal logistics warehousing, overseas engineering and other fields.  In recent years, Huazhong Electric Power Design and Research Institute Smart Energy Company has undertaken the general contracting and design work of a large number of new energy projects. In this exchange meeting, firstly, the current status of lightning protection design of photovoltaic projects at home and abroad was introduced, combined with IEC61643-32:2017 Low-voltage surge protector (SPD) Part 32: Electricity of photovoltaic installations Selection and use guidelines, introduce the design of SPD parameters under different conditions whether there is LPS on the side of the photovoltaic power generation unit, and introduce the solutions of photovoltaic box transformers, wind power box transformer lightning protection products, combined with actual cases. and selection considerations.

The electronic truth is: the use of the electric field change rate alarm is actually a kind of identification alarm after lightning occurs, and the data accuracy is far lower than the data of the lightning location system. The use of rate-of-change early warning itself is based on external electrical changes, which has already represented the occurrence of lightning, so the electronic probe is not a real atmospheric electric field meter, and the early warning lags behind the field grinding type. ●Selected materials can resist acid pollution and are suitable for various harsh environments. ●The system can be networked and can be used in conjunction with other meteorological equipment. ●Can realize remote monitoring. ●Established a multi-product database system for data storage and analysis. By continuously sampling the atmospheric electric field at the installation site by the atmospheric electric field meter, we can know the local electric field intensity, and when a thunderstorm occurs, the electric field intensity will change sharply. A lightning imminent warning occurs. Lightning early warning system is currently recognized as one of the most effective measures to greatly reduce lightning casualties and disasters.

Anhui Jinli lightning early warning system adopts field grinding electric field meter, which is a highly centralized software and hardware system integrating atmospheric electric field intensity monitoring and lightning near-warning. The field grinding lightning early warning system adopts DC brushless motor to It rotates at a uniform speed to realize the switching between shielding and non-shielding of the stator. The stator is an electric field induction surface, so as to obtain a changing current signal (Q=ε*S*E). It uses the measured electric field, electric field change rate, electric field mean value three Method technology can achieve 0% false alarm rate. The truth of the field grinding probe is: the anti-interference ability is relatively strong, the collected electric field value data is accurate and stable, and it can achieve early warning even if the first lightning occurs locally.

Large oil and gas depots have always been a high-risk area for lightning protection. In January 2022, the State Council Work Safety Committee issued the "National Centralized Control Plan for Safety Risks of Hazardous Chemicals" (hereinafter referred to as the "Governance Plan"). "Some large oil and gas storage bases such as national oil reserves have a low level of intrinsic safety, and the "four systems" of emergency shutdown, gas detection, video surveillance, and lightning early warning are imperfect." On February 24, the Ministry of Emergency Management became dangerous In accordance with the requirements of the Work Plan for Implementing Safety Risk Management and Control Measures for Large-scale Oil and Gas Storage Bases issued by the State Council Security Committee, the Second Division of Supervision and Management organized the compilation of the Basic Requirements for Lightning Early Warning Systems for Large-scale Oil and Gas Storage Bases (for Trial Implementation) Basic Requirements for Emergency Shutdown Systems for Gas Storage Enterprises (Trial Implementation)" to ensure that large-scale oil and gas storage bases are equipped and applied with lightning warning systems and rectification of emergency shutdown system problems before June 30, 2022.
