What is the substation information point table, the information point table of NARI Technology

The list of information points, the name, definition and sequence list of telemetry, remote signaling and remote pulse collected by various equipment in the substation, and the name, definition and sequence list of remote control and remote adjustment defined by the operating equipment; This is a rough understanding of the information point table. The secondary automation equipment on the substation collects various information, such as voltage and current, and must be sent to the power supply bureau.

scheduling automation system (such as the D5000 currently used by the State Grid, of course, D5000 is not only an automation system, I don't know how powerful, to be exact, it should be a platform, and the scheduling automation system is only one of the parts); There is usually a communication management device on the station, which receives most of the information collected by the automation equipment, and then the communication management device sorts and sorts the information, and then ** out to D5000. The collection of all the information organized and sorted by the communication management device is the so-called information point table, from which each collected information can be corresponded. It's just a very rough personal understanding.

Generally speaking, it refers to the "four remote" signals for the main and substation in the substation communication, that is, the information sorting point table of remote signaling, telemetry, remote control and remote adjustment, which is convenient for dispatchers to collect, observe and process relevant site location information.

For information point tables.

In Zhuhai Yitong, there is a perfect point meter management system software, transmission verification software, point system, etc.

Generally speaking, the information point table of the substation is a summary table used to collect the specific points of the substation operation and monitoring data. The following should be included:

1. Equipment operation status point: the status point of the switch (circuit breaker) and knife switch (isolation switch) at the above 11 intervals is the name of the switch knife switch and its auxiliary contact.

2. Equipment operation parameter points: bus voltage (including phase voltage, line voltage), frequency; voltage, current, active power and reactive power of the incoming line of the power supply; The current of each load interval (the transformer can require the current on the high-voltage side, or on the high-voltage side), active power, and reactive power; The current of the bus tie spacing.

3. Equipment measurement parameter points: active and reactive energy of the power supply incoming line; Active energy at load intervals.

If there are no special requirements, the content of the above points should be able to meet the needs of operation monitoring.

The most important thing in integrated wiring is statistics and marking, one-to-one standardization.

On the basement level, the information point only needs to be in the gatehouse.

Shopping malls, a little more as needed, so that after renting out, each shop has a point.

There are at least 2 points for an office in an office building and one point for a room in a hotel.

What you want is a point table with remote signaling, remote control, telemetry and other information. NARI Technology's no, Shenzhen NARI's or not.

The telecontrol protocol is used to learn to use , CDT, as well as 103 for protection and 102 for electrical energy. There are four remote roll calls in the telecontrol information table, namely telemetry, remote signaling, remote control, and remote adjustment.

The telecontrol information table is the name and order of the four remote information of the master station uploaded in these protocols. Let's take the example of a remote signal point table

Point Sequence Number Roll call description.

1. The switch position of the high-voltage side of the main transformer is 2 220kV bus tie switch position.

The sub-station uploads packets in this order, and the dispatching master parses and decodes packets in this order.

When uploading telemetry and remote control packets, the dispatching master performs packet analysis in the order of the point table.

I haven't heard of this name.

If there is an information table, it can be convenient for the staff of the scheduling, monitoring, automation, maintenance and other departments to create, modify, compare, and review and confirm the point table.

Zhuhai I-Access designed a point meter management system, a system that can be processed on the same platform. It can solve the information management of information points and tables.

1. Non-standardization; The workload of the compilation and review of the point table is large and the efficiency is low; The comparison of points and tables needs to be carried out manually, and the error rate is high. It has the characteristics of multi-vendor point input, single format standard source storage, multi-input source comparison and correction, multi-manufacturer point output, automatic point alignment, attachment storage, version control and so on.

I have to provide some information about what information you need on the statistical table. What data needs to be used on the table, whether the data needs to be organized and analyzed, nothing is provided, and it cannot be designed**.
