Substation integration business management system interconnection

Huang Fengmin, a pre-sales support engineer of Shenzhen Langchi Xinchuang Technology Co., Ltd., introduced: “Users have implemented some video monitoring, dynamic monitoring and integrated alarm systems in their respective systems, but most of them are implemented step by step and in batches, and the systems operate independently. Even each system requires independent management personnel, which makes it difficult to achieve comprehensive monitoring and centralized management of multiple systems, virtually reducing the efficiency of the system and increasing the management costs of the system. Mainly based on data monitoring, combining multiple alarm functions, and integrating multiple systems at the same time.” At the same time, with the centralized procurement of power grid companies, the gradual upgrading of products, and the maturity of technology products and improvement of bandwidth resources, the following Although various levels still need to be steadily matured at this stage, it is foreseeable that in the near future, there will be substantial progress in the absence of a substation.

1. Integration of large-scale systems for business management

It is very common to integrate the systems involved in a base station into a single platform for management. However, under the current technology, it is still difficult to fully integrate the security system with the original “four remote” systems because the management platform also has Not mature enough. Therefore, the current substation unattended system is basically operated and managed separately from the “four remote” system. It is worth mentioning that, in more mature projects, security-related subsystems can already be centralized into one management platform. Correspondingly, the other four Remote can also be integrated into a unified platform for management.

Huang Guanfeng, technical support engineer of Guangzhou Meidian Bell Electrical Technology Co., Ltd., explained the reasons for the slow development of platform integration: “System integration is not a matter of simple integration. It is especially unattended in substations and involves many equipment operation data. The problems encountered are even more.In this case, how to achieve the pre-plan and linkage is difficult.On the other hand, the developer of the demand management platform is well aware of the significance of each data in the power industry. Based on this, we consider how to plan a management interface that better meets the needs of customers. At present, the platforms on the market are all based on video surveillance, and then integrate some important security requirements. At the same time, he also said: "According to the market reaction, related Enterprises have already started research and development, and the more problem is that among the many requirements, which system integration is the main one and how to integrate it into the large platform, that is, in the development of specific modules, depending on the degree of importance of the subsystem, there will be A development integration of the points."

2, compatible

Compatibility can be achieved through the formulation of industry standards (such as the Guangdong Power Grid company substation environmental video surveillance system enterprise standard) to unify the agreement to achieve compatible access between products, subsystems, and platforms from different vendors. And comply with the current industry related agreements, such as: support DB33 protocol can achieve interoperability with third-party platforms; support the International Open Network Video Interface Forum (ONVIF) protocol to achieve compatible access to multi-vendor devices. It can be said that with the development of the network, compatibility is no longer a problem. It can meet the requirements of the private network and protocol specifications of various industries. In addition, integrators can also tailor system communication protocol standards for industry users to meet the needs of industry customers for deep customization, emphasize unified planning and deployment, unified management and control, achieve effective compatibility with heterogeneous networks, and implement different protocol networks. Data exchange and transparent access between application systems meet industry-specific application functions.

3, plan

Unattended demand equipment is extremely stable because no one can intervene in the event of an unexpected situation. At this time, the system needs to have certain 'correction' capabilities, and through the preparation of a number of pre-set solutions to solve the various situations that may arise. That is, when the system is designed, starting from the particularity of electricity, taking into account all possible conditions, make a corresponding plan.

The degree of perfection and development of the plan also affect the process of system integration. The difficulty is that demand-related manufacturers go deep into the industry to understand their operating models and know the meaning of each data in the “four remote” systems before they can make plans that fit the industry and are actually available.
