Problems solved by technology

[0007] (1) There is an uncontrollable risk of misoperation during the acceptance process, which may cause the relay protection equipment of the substation to be in an abnormal operating state, violate the principle of safe operation, and cause the relay protection equipment to malfunction or refuse to operate;
[0008] (2) When a problem occurs, it is difficult to carry out on-site rectification of the operating equipment in some cases, especially for smart substations. If it is necessary to re-download and configure the protection device, the running relay protection device must be out of operation, and it will be re-installed invisibly. magnified security risks;
[0009] (3) The existing acceptance method has a long acceptance cycle and involves complex cooperation between personnel and units
[0011] (1) The system wiring is complicated, the software and hardware are used together, and the interface settings are cumbersome;
[0012] (2) The level of hardware investment is high and the versatility is poor. Different manufacturers need to match different telemotors

Embodiment 1

[0036] Embodiment 1: The substation remote monitoring system usually includes various protection devices to be monitored in the substation, a remote machine for realizing communication between the protection devices and the remote monitoring system, and a background machine for monitoring each protection device, etc., thereby forming a connected monitoring network. Among them, the protection device sends telemetry and remote signaling information to the remote monitoring system and the background computer, and both the remote monitoring system and the background computer can send remote control instructions to the protection device, and can receive feedback signals returned by the protection device based on the remote control instructions. The above functions need to be verified.

Abstract

The invention relates to an all-digital simulation verification system, which is used to realize the configuration verification of the remote monitoring system of a substation. The digital analog remote control device for the remote machine in the analog substation remote monitoring system, the digital analog monitoring background for the background machine in the analog substation remote monitoring system; the digital analog protection measurement and control device, the digital analog remote control device, the digital The analog network system of the analog substation remote monitoring system is formed by connecting with the analog monitoring background. The present invention also provides a verification method adopted by the above-mentioned all-digital simulation verification system. The invention solves the configuration verification problem of the substation remote monitoring system, can be applied simply and flexibly, improves verification work efficiency, has better versatility and adaptability, and can also reduce safety risks in system verification.

Description

technical field [0001] The invention belongs to the field of electric power system substation automation, and in particular relates to an all-digital simulation verification system and a verification method for realizing configuration verification of a remote monitoring system of a substation. Background technique [0002] Substation remote monitoring system, as the core link of unattended substation monitoring and control, plays an extremely important role. With the continuous construction, reconstruction and expansion of substations, the verification workload of the remote monitoring system of substations is increasing. The current monitoring system verification technology is basically realized by the actual verification method of the operation monitoring system. The structure diagram of the verification system is shown in the attached figure 1 shown. At present, the verification of the substation monitoring system must wait until the other work of the entire substation ...
