Embodiment 1

[0069] The present invention is a substation setting state access controller and a system control method. The controller is connected with various comprehensive monitoring units in the station and the substation equipment state access controller through the substation I1 interface.

[0070] The state access controller of the substation equipment is connected to the substation CAG at the provincial company side through the substation I2 interface to realize the access of the substation status information.

[0071] The status access controller of the substation equipment supports 3-slot extended passive backplane, uses Intel LGA775 package Core 2 FSB 800MHz processor, provides 2 10 / 100 / 1000MBps RJ45 network interfaces, 2 serial ports, 1 VGA, 4 USB , 1 KB / Mouse interface, power supply: support PS / 2 ATX 300W.

[0072] Transformation equipment state access controller supports ATX power supply from the backplane to avoid the control connection between the backplane and the mainboa...

Abstract

The invention relates to the technical field of monitoring systems, in particular to a condition acquisition controller (CAC) for power transformer equipment and a system control method. On a station level of an intelligent substation, the CAC for the power transformer equipment is connected with a comprehensive monitoring unit in the intelligent substation or an intelligent electronic device (IED) with the function of the comprehensive monitoring unit through an interface I1; and the CAC for the power transformer equipment is connected with a condition acquisition gateway (CAG) of a grid company in the province through an interface I2, so that the power transformation condition information can be accessed, and the aim of managing the condition information of the power transformer equipment can be fulfilled. The CAC has the complete functions of data analysis and diagnosis, the condition information of a primary device is provided, and the possible faults are pre-warned; and the health condition of the equipment is estimated. The CAC has significance to avoiding accidents of electrical equipment, and guaranteeing that the equipment is safe and reliable and runs normally.

Description

technical field [0001] The present invention relates to the technical field of monitoring systems, in particular to a state access controller for substation equipment and a system control method. Background technique [0002] The types of substation equipment and the diversity of sensor technologies lead to the heterogeneity and dispersion of the current front-end subsystems, which is not conducive to the unified deployment and promotion of the substation equipment condition monitoring system in the company. The system design needs to establish an extensible status information access specification layer that can access various status monitoring data at a moderately advanced position to achieve standardized access to status information. At the same time, it is necessary to improve the "concentration" and "direct availability" of the access status information at the access specification layer, and shield the original monitoring data related to specific sensor technologies to ...
