What is power system automation technology? What is power system relay protection and automation

Power system automation includes the automation of power generation control and the automation of power dispatching. Automation of power generation control has been achieved, but further development is needed. The automation of power dispatching includes comprehensive programs for online power flow monitoring and fault simulation, as well as the automation of distribution networks. At present, the most popular thing is the comprehensive automation of substations, that is, the construction of integrated substations to achieve better unattended operation. In addition, the dispatcher training simulation system (DTS) facilitates dispatcher learning. Distribution Automation (DAS) is already here, but further development is needed.

Realize automatic control, automatic dispatch and automatic management of electric energy production, transmission and management. The power system is a large, complex system with unified dispatch and operation consisting of power plants, substations, transmission and distribution networks and users with a vast geographical distribution. The field of power system automation includes automatic detection, regulation and control of the production process, automatic safety protection of systems and components, automatic transmission of network information, automatic scheduling of system production, and automated economic management of enterprises. The main goal of power system automation is to ensure the quality of power supply (frequency and voltage), ensure the safety and reliability of system operation, and improve economic benefits and management efficiency.

According to the production and distribution process of electric energy, power system automation includes grid dispatching automation, thermal power plant automation, hydropower station comprehensive automation, power system information automatic transmission system, power system anti-accident automatic device, power supply system automation, and the electric power industry Management system automation and other 7 aspects, and form a hierarchical and hierarchical automation system (see figure). Regional dispatch centers, regional substations and regional power plants form the lowest level; the intermediate level consists of provincial (municipal) dispatch centers, hub substations and directly affiliated power plants, and the general dispatch center forms the highest level. In each level, power plants, substations, distribution networks, etc. constitute multi-level control.
