Introduction
The safe, reliable, economical and efficient operation of the power system is important for ensuring national energy security and promoting sustainable economic and social development
Meaning. In order to guide the scientific development of the power system and promote the coordination of planning, design, operation and other majors, the original industry standard ``Power System
On the basis of the experience of the “Power System Technical Guidelines”, while this simultaneous revision of the “Power System Security and Stability Guidelines”, combined with the future energy strategy
The development trend of transformation, the compilation of "Power System Technical Guidelines" was completed. This standard clarifies the main technical principles and
Methods, ranging from power supply arrangement and access, inter-system tie lines, DC transmission systems, transmitting and receiving end systems, reactive power compensation and voltage control, and full power system
Technical requirements are put forward in terms of recovery after shutdown, relay protection, safety automatic devices, dispatch automation, and power communication systems.
Power System Technical Guidelines
1 Scope
This standard specifies the basic technical requirements for power systems, power supply arrangements, power supply access, inter-system tie lines, DC transmission systems, transmission
Receiving end system, reactive power compensation and voltage control, power system recovery after full shutdown, relay protection, safety automatic device, dispatch automation, power communication
Letter system and other requirements.
This standard applies to power systems with voltage levels of 220kV and above. Power systems below 220kV (including distributed power sources) can
Refer to execution.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Powersystem
It consists of power generation, power supply (transmission, transformation, distribution), electrical equipment, and relay protection and safety automatic equipment required to ensure its normal operation.
A unified whole constituted by secondary equipment such as deployment, dispatch automation, and power communications.
3.2
New energy station
All equipment below the grid connection point of wind farms or solar power stations that are integrated into the power system.
Note. Including transformers, bus bars, lines, converters, wind turbines, solar power generation systems, energy storage and auxiliary equipment, etc.
3.3
Load reserve capacity loadreserve
The reserve capacity of the system that is connected to the bus and can be loaded immediately to balance the power fluctuation and prediction caused by the instantaneous load or new energy
The deviation between.
3.4
Accident reserve capacity
The power capacity that can be used within a specified time after an accident occurs in the power system.
3.5
Maintenance reserve
In order to ensure that the power generation equipment in the system is regularly overhauled without affecting the power supply, according to the system's hydropower, thermal power, nuclear power coordination and annual load
Set as the reserve capacity for regular maintenance of power generation equipment under changes and other circumstances.
