1 Scope
This standard outlines the procedures and requirements for the inspection and management of equipment in photovoltaic power plants. It is specifically designed to ensure the safe, efficient, and systematic operation of photovoltaic systems within the New Energy Power Generation Department of the Upper Yellow River Hydropower Development Co., Ltd. The scope of this document includes all photovoltaic power stations under the jurisdiction of the company. It provides a structured approach to equipment monitoring, maintenance, and safety compliance.2 Normative References
The following documents are essential for the proper application of this standard. For references with specific dates, only the specified version applies. For references without dates, the latest version, including any amendments, is considered valid. - China Power Investment Corporation's "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 ensuring its effective execution across all photovoltaic facilities. It also oversees the review and revision of the system based on feedback from field operations. The department works closely with photovoltaic stations to align inspection routes, content, and requirements with the operational procedures. 3.2 **Photovoltaic Power Station** Each photovoltaic power station is required to strictly follow the "Planned Inspection System" and ensure that all inspections are carried out accurately. They must establish detailed inspection routes, contents, and requirements in accordance with their own operational procedures. Any issues or suggestions identified during the implementation process should be promptly reported to the Safety Production Management Department for further action.4 Management Requirements
4.1 **Inspection Procedures and Requirements** Inspections are categorized into several types: shift handover inspections, pre-shift inspections, intra-shift regular inspections, and mobile inspections under special conditions. Each type has specific timing and procedures to ensure comprehensive coverage of all critical equipment. The inspection schedule, route, and details must be clearly defined in the power station’s "Operational Procedures" and strictly followed. Inspectors must thoroughly check every part of the equipment, listening, touching, and analyzing where necessary. No suspicious points should be overlooked. During inspections, personnel must adhere strictly to both the inspection system and operational procedures. All equipment within their responsibility must be inspected carefully and according to the set frequency, time, and content. No shortcuts or careless practices are allowed. All equipment, whether in operation or on standby, must be inspected as required. At least two detailed inspections per month should be conducted for each group of equipment. Before starting an inspection, staff should review defect records and shift logs to focus on previously identified issues. Each inspection must be documented accurately, and any defects found should be reported immediately. In case of abnormal conditions, prompt action must be taken to prevent accidents. Emergency situations should be handled according to the "Operational Procedures." Inspectors must carry necessary tools such as flashlights and test pens. During peak load periods, additional mobile inspections of key equipment like the main transformer and distribution room should be conducted daily. In certain situations, such as when equipment has significant defects, after major repairs, or during extreme weather conditions, the number of inspections or fixed-point monitoring should be increased. 4.2 **Safety Precautions** During inspections, staff must remain focused and avoid distractions unrelated to their work. They must follow the "Working Safety Regulations for Electric Power Production" and pay attention to the following: - Maintain a safe distance from live parts; do not cross fences or remove nameplates. - If approaching high-voltage equipment, a supervisor must be present, and strict safety distances must be maintained when the equipment is not powered off. - Do not tamper with equipment or touch live parts or other hazardous components. - When high-voltage equipment is grounded, stay at least 4 meters indoors and 8 meters outdoors. Personnel entering these areas must wear insulated boots and gloves. - During thunderstorms, wear insulated boots when inspecting outdoor high-voltage equipment, and avoid proximity to lightning arresters and rods. - If any unauthorized or unsafe activities are observed, they must be stopped and reported to the shift supervisor. If the supervisor cannot act, the issue should be escalated to the project manager.5 Inspection and Evaluation
5.1 If the inspection duration, routes, or content is not clearly defined in the "Operational Procedures," the individuals responsible for drafting, reviewing, and approving these regulations will be held accountable. 5.2 Failure to comply with this standard may result in disciplinary actions based on the company's violation assessment policies.Double Spring Washer,Spring Tension Washer,stainless steel washer,spring stainless steel
