技术领域technical field
本发明属于电力检测技术领域，特别涉及一种继电保护自动闭环检测方法。The invention belongs to the technical field of electric power detection, in particular to an automatic closed-loop detection method for relay protection.
背景技术Background technique
就地化继电保护装置就地安装于一次设备附近，取消了液晶界面，对外采用标准的连接器，其试验方式与常规保护不同，现场试验工作开展困难，大量试验工作需要在工厂进行。目前，就地化继电保护装置检测主要存在以下突出问题需要解决。The in-situ relay protection device is installed near the primary equipment, the liquid crystal interface is canceled, and the standard connector is used externally. The test method is different from the conventional protection. It is difficult to carry out the on-site test work, and a large amount of test work needs to be carried out in the factory. At present, the following outstanding problems need to be solved in the detection of in-situ relay protection devices.
(1)就地化保护还未形成成熟的标准化检测体系(1) In-situ protection has not yet formed a mature standardized detection system
就地化二次设备与传统继电保护设备相比存在诸多差异性。一是就地化保护装置取消液晶面板设计，需要结合装置的MMS、GOOSE信息及保护管理单元信息等开展测试工作，其检测工作相较于现场更适宜在实验室或厂内开展；二是就地化继电保护装置的接口形式发生变化，传统继电保护测试模式及试验仪器不再适用；三是目前就地化保护装置的检测内容、检测流程及检测模式仍在探索之中，尚未形成标准化的检测体系。这些都是就地化保护检测工作面临的难题。There are many differences between in-situ secondary equipment and traditional relay protection equipment. One is to cancel the LCD panel design of the in-situ protection device, and it is necessary to combine the MMS, GOOSE information and protection management unit information of the device to carry out testing work. Compared with the field, the testing work is more suitable for carrying out in the laboratory or factory; The interface form of the in-situ relay protection device has changed, and the traditional relay protection test mode and test instruments are no longer applicable; third, the detection content, detection process and detection mode of the in-situ protection device are still being explored and have not yet been formed. Standardized detection system. These are the difficulties faced by in-situ protection testing.
(2)缺少变电站实际运行数据开展就地化保护实景验证(2) Lack of actual operation data of substations to carry out real scene verification of in-situ protection
目前，继电保护测试手段仍主要是通过相对独立的试验装置，模拟采样及一次设备信号，开展装置单体性能及简单的开入、开出验证，尚不具备同时模拟全站运行数据的试验测试能力，不具备装置功能级半实物仿真，无法开展设备间的系统级测试，难以实现设备现场即插即用。设备发往现场后仍需开展大量系统性验证工作，一方面工作量大。另一方面也带来安全风险。此外，就地化保护工作要求继电保护装置的主体检测工作提前至实验室或厂内开展，而实验室或工厂内缺少变电站实际运行数据，无法开展就地化保护实景验证，无法实现二次设备装置级仿真和动模级仿真。At present, the relay protection test method is still mainly through a relatively independent test device, simulating sampling and primary equipment signals, and carrying out the verification of the performance of a single device and simple switch-in and switch-out, and there is no test that simulates the operation data of the whole station at the same time. The testing capability does not have the hardware-in-the-loop simulation at the device function level, and it is impossible to carry out system-level testing between devices, and it is difficult to realize on-site plug-and-play of devices. After the equipment is sent to the site, a lot of systematic verification work still needs to be carried out. On the one hand, the workload is heavy. On the other hand, it also brings security risks. In addition, the on-site protection work requires the main detection work of the relay protection device to be carried out in the laboratory or factory in advance, but the laboratory or factory lacks the actual operation data of the substation, and it is impossible to carry out the actual scene verification of the on-site protection, and it is impossible to realize the secondary protection. Equipment level simulation and dynamic model level simulation.
(3)继电保护常规检测方法无法满足工厂化大规模检测需求(3) Conventional detection methods for relay protection cannot meet the large-scale detection requirements of factories
目前，继电保护常规检测仍停留在人为完成试验配置、装置接线等操作后，通过施加激励并观察响应，开展试验检测工作的阶段。此种模式对专业人员及试验设备的依赖程度高，且工作量大，在实验室或工厂化内完成保护装置大规模检测的实际需求难以得到满足。同时校验手段的受限、校验内容的不全面以及校验结果的主观性判断导致了试验的评判标准、检测结果存在差异性，也为继电保护设备安全稳定运行埋下隐患。如何利用就地化保护接口、尺寸、信息交互标准化等优势，形成新型流水线检测模式，以满足大规模检测需求，是就地化保护工作开展工作中的一项难题。At present, the routine detection of relay protection still stays in the stage of carrying out the test and detection work by applying excitation and observing the response after man-made operations such as test configuration and device wiring. This mode relies heavily on professionals and test equipment, and the workload is heavy. It is difficult to meet the actual needs of large-scale testing of protective devices in laboratories or factories. At the same time, the limitation of the verification means, the incompleteness of the verification content and the subjective judgment of the verification results lead to differences in the evaluation standards and test results of the test, and also lay hidden dangers for the safe and stable operation of the relay protection equipment. How to use the advantages of in-situ protection interface, size, and information exchange standardization to form a new pipeline detection mode to meet the needs of large-scale detection is a difficult problem in the development of in-situ protection work.
