Abstract

The invention provides a temperature control device and method of a series compensation device control protection system. The device comprises an acquisition module, a processing module and an adjusting module which are connected in sequence; the acquisition module converts the acquired actual temperature of the control protection system into a differential signal of a high voltage level; the processing module is used for calculating the operating temperature of the control protection system; and the adjusting module is used for adjusting the actual temperature of the control protection system. The actual temperature can be adjusted on the basis of the calculated operating temperature, the automation degree is high, and the control protection system and a draught fan cannot be damaged; andcollection of the overall temperature of a case is achieved by arranging a plurality of temperature sensors, safe and stable operation of the control protection device and the measurement and controldevice is guaranteed, damage caused by too high temperature is avoided, in addition, the operation temperature of the control protection system can be displayed and stored, and convenience is provided for maintenance of the control protection system.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a temperature control device and method for a series compensation device control and protection system. Background technique [0002] The series compensation device is connected in series in the AC transmission line, which can increase the transmission capacity of the AC system, improve the static stability of the AC system, and also have the advantages of reducing network loss. Assure. [0003] The control and protection system is mainly composed of two parts: the control protection device and the measurement and control device. It monitors the analog and remote signal values ​​of the series compensation device in real time. Analog quantities include capacitor bank current, capacitor unbalanced current, line current, metal oxide voltage limiter current, spark gap current and valve group current, etc.; remote signaling quantities include bypass circuit breaker position sig...
