1. Scope
This standard outlines the procedures for inspecting and managing equipment at photovoltaic power plants. It is specifically applicable to photovoltaic power stations under the New Energy Power Generation Department of Upper Yellow River Hydropower Development Co., Ltd.2. Normative References
The following documents are essential for the application of this standard. For referenced documents with a specific date, only the version stated in the document applies. For references without a specified date, the latest version (including all amendments) is applicable. - China Power Investment Corporation "Working Safety Regulations for Electric Power Production" - "Administrative Measures on Production and Operation of New Energy Projects of China Power Investment Corporation" - "China Power Investment Corporation New Energy Management Regulations" - "Operation Management System for Hydropower Stations of the Upper Yellow River Hydropower Development Co., Ltd."3. Responsibilities
3.1 **Safety Production Management Department** This department is responsible for implementing the "Planned Inspection System for Photovoltaic Power Plant Equipment" and overseeing its execution across all photovoltaic facilities. They must ensure that inspection routes, content, and requirements are aligned with the photovoltaic station's operational procedures. Additionally, they are tasked with collecting and implementing feedback on the inspection system, as well as organizing necessary revisions. 3.2 **Photovoltaic Power Station** Each photovoltaic power station is responsible for implementing the planned inspection system and ensuring its accurate execution. They must establish inspection routes, content, and requirements based on their operational procedures. Any issues or suggestions identified during implementation should be reported to the safety production department in a timely manner.4. Management Requirements
4.1 **Inspection Procedures and Guidelines** Inspections are categorized into several types: shift handover inspections, pre-shift checks, in-shift regular inspections, and mobile inspections conducted under special conditions. Shift handover inspections occur when personnel arrive at the site until formal handover is complete. Pre-shift checks involve a one-hour tour before starting work. In-shift regular inspections are conducted during the middle of the shift, while mobile inspections are performed under exceptional circumstances. All inspection schedules, routes, and content must be clearly defined in the station’s "Operational Procedures" and strictly followed. Inspectors must visit every designated location, listen to any unusual sounds, touch relevant components, and analyze any suspicious findings. Each inspection must be thorough, detailed, and conducted in accordance with the required frequency, timing, and content. No shortcuts or negligence should be allowed. Spare equipment must be treated equally to operating equipment and inspected according to the same standards. At least two detailed inspections per month should be conducted for each group of equipment. Before each inspection, staff should review defect logs and shift records to pay extra attention to defective or recently repaired equipment. Each inspector must take full responsibility for their tasks. Any defects found should be promptly reported, and after completing the inspection, all data must be recorded accurately in the report. In case of abnormalities, immediate action must be taken and reported to the responsible person to prevent accidents. In the event of an emergency, on-duty personnel must follow the "Operational Procedures" to address the situation. Necessary tools such as flashlights and test pens should always be carried during inspections. During peak load periods, an additional mobile inspection of the main transformer and distribution room equipment should be conducted daily. The number of mobile inspections or fixed-point monitoring should be increased in the following situations: - When significant defects or abnormalities are present in the equipment. - When new or newly overhauled equipment is in operation. - During extreme weather conditions such as strong winds, heavy rain, high temperatures, heavy snow, or severe cold. - When there is a weak point in the equipment or after a defect has been addressed. - When equipment is operating near or at rated parameters. - When additional mobile inspections are deemed necessary by management. 4.2 **Safety Precautions** During inspections, personnel must remain focused and avoid any activities unrelated to production. All inspections must comply with the "Working Safety Regulations for Electric Power Production." Special attention must be given to maintaining safe distances from live parts, not crossing fences or removing nameplates. If approaching high-voltage equipment, a supervisor must be present, and strict safety distances must be maintained when the equipment is not de-energized. It is strictly prohibited to tamper with equipment or touch live parts or other hazardous components. When high-voltage equipment is grounded, indoor personnel must stay at least 4 meters away from the fault point, and outdoor personnel must maintain a distance of at least 8 meters. Those entering these areas must wear insulated boots and gloves when touching equipment housings or structures. During thunderstorms, when inspecting outdoor high-voltage equipment, insulated boots must be worn, and personnel should avoid approaching lightning arresters and rods. If staff are found violating safety regulations or performing unauthorized work during inspections, they must be stopped immediately and reported to the shift supervisor. If the supervisor cannot resolve the issue, it should be escalated to the project manager.5. Inspection and Evaluation
5.1 If the duration of inspections, routes, or content and requirements are not clearly outlined in the "Operational Procedures," the individuals responsible for establishing, reviewing, and approving the regulations will be held accountable. 5.2 Failure to implement this standard will result in evaluation and disciplinary actions according to the company's violation assessment policies.
