and other links, this part of the work still needs electrical personnel to complete. In addition, in the process of engineering construction, the electrical power consumption and receiving part of the electrical plant need to be debugged and put into operation in advance. In the electrical control function part, namely the sequence control (SCS), it is still recommended to set up a separate electrical controller to facilitate the smooth progress of the actual work. The data acquisition part is required to be integrated with thermal engineering.
4.2 Description of software Functions
4.2.1 DAS function of data acquisition system
The data acquisition system (DAS) should continuously collect and process all important measuring point signals and equipment status signals related to the electrical system, so as to provide relevant operation information to the operator in time and realize the safe operation of the unit. Once the unit occurs any abnormal conditions, timely alarm, improve the unit utilization rate. Generally have the following functions.
(1) Display: including operation display, group display, bar chart display, trend display, alarm display, etc.
(2) Tabulation records: including regular records, accident recall records, sequence of events (SOE) records, trip list, etc.
(3) Historical data storage and retrieval.
(4) Secondary calculation and unit performance.
4.2.2 Sequential control system SCS(G/A) function
The sequence control of electrical part is mainly composed of three functional groups:
(1) Generator – transformer function group, which includes the following sequential control sub-group items:
Item of high-voltage side circuit breaker and tool brake of generator – transformer group: The sub-item includes high-voltage side breaker of generator – transformer group and ⅰ-
