Group revision: GE series

The line protection panel is an important part of the power system, mainly used to protect, measure and control the function of the corresponding spacing of the power station 1. The following is a detailed introduction to the line protection panel:

Main functions:

Protection function: DS200LPPAG1AAA line protection panel has a variety of protection functions, such as quick break protection, limited speed break, overcurrent protection, reclossing, overload, zero sequence overcurrent, low frequency load shedding, low voltage, bus grounding, PT break, etc. 1. These protection features are designed to ensure the stable operation of the power system and prevent system failure due to voltage instability or other potential hazards.

Measurement function: The line protection panel can measure the voltage change, so that the voltage runs in a stable status2.

Control function: DS200LPPAG1AAA line protection panel can reasonably control the floating range of voltage to ensure the safe and stable operation of the power system2.

Structure and classification:

Hard plate: This is a hardware device such as a connection piece in the protection cabinet, and is a bridge and link between the protection device and the external secondary circuit. Hard platen is divided into functional platen and outlet platen. The DS200LPPAG1AAA function plate mainly realizes the functions of the protection device, such as differential protection, distance protection, etc., and the outlet plate determines the final result of the protection action.

Soft plate: This refers to the rejection of a certain function of the protection device software system, which can be achieved by modifying the software control word of the protection device. Unlike hard platen, soft platen is a program, not a physical object.

Application:

DS200LPPAG1AAA line protection device is mainly used in large substations, power plants and other places. The power system in these places covers a wide area and needs to withstand a large capacity of voltage, so it is prone to voltage instability. The existence of line protection panel can play a substantial role in protecting the huge power system.
