The PMCS Energy Management Control System is a standardized energy management control system introduced by ABB. This standardized system can monitor and manage various electrical equipments such as high, medium and low voltage of users, and solve the problem of high energy consumption and low efficiency of traditional enterprises, which can effectively improve power supply reliability and power efficiency through energy Reasonable arrangement and scientific utilization to achieve the purpose of energy conservation and emission reduction.
MCS energy management control system structure generally consists of three parts:
1) Management layer
The management of the PMCS energy management control system consists of one or more servers, workstations, Ethernet switches, printers, etc. Its main task is to collect various information of the field devices and establish a database. Through the friendly human-machine interface and powerful data processing capabilities, real-time monitoring of the running status, operating parameters and fault information of the field devices, and remote control of the equipment, is the interface between the system and the operating personnel.
2) Communication layer
The main task of the communication layer is to collect various local information and upload the information to the management layer via Ethernet to realize the functions of monitoring, measuring and controlling the field devices.
3 ) Device layer
The equipment layer consists of relay protection devices, multi-function meters, multi-loop monitoring devices, and other intelligent acquisition devices. The PMCS energy management control system adopts a layered and distributed design idea. The system structure is divided into three layers of network structure: management layer, communication layer and equipment layer.
Failure of the system network does not affect the measurement and protection functions of the field device layer devices. Management's PMCS energy management control system software provides clear and transparent types electrical parameter data, through which the administrator can clearly understand the operation and energy consumption of each device.
PMCS energy management control system software can easily perform power parameter information query and remote remote control and remote adjustment of the system through a modular function interface. The system software provides easy access to various functional module interfaces through a main portal interface:
— Basic function module interface: geographic location information function module interface, electrical system graphic monitoring function module interface, system information report management function module interface, system log management function module interface, etc.
— Advanced function module interface: system network monitoring function module interface, grid quality management function module interface, power management function module interface, load management function module interface, etc.
