2.1 , standby power source to function
Improve power system reliability methods generally have the following : First, the use of ring power supply reliability such a way that greatly improved, but the multi-stage ring detrimental to system stability , low-voltage grid in less used ; another way to improve the reliability of power supply is a dual power supply , which will bring with difficult issues such as protection . Therefore , in the low-voltage power grid in the wider selection of single power supply when the power failure is not the normal way to automatically switch to standby power supply in another way .
More types of wiring in the form of a standby power , standby logic cast a greater difference . Conventional devices are often prepared to vote in accordance with the specific requirements need to modify the logic of the computer equipment you need to prepare to vote to amend the relevant software , increasing the workload of the engineering design , equipment investment and reduce the reliability of the equipment . A device to be able to adapt to different requirements, SAI-388D digital standby power source device, graphical interface based programmable logic way to achieve functional equipment investment
Programmable logic equipment investment principles :
SAI-388D digital standby power source device ( hereinafter referred to as the standby switch device ) offers 13 analog inputs , 7 digital inputs , 8 voltage setpoint , six current setpoint , eight time setting , 5 paid to independent contact output. Value and all inputs can be a programmable control equipment investment and action elements . Equipment investment means every action logic control conditions can be divided into two categories: one is allowed to condition , and the other for the lockout condition . When permitted conditions are met, while blocking condition is not met , the equipment investment and exports action . To prevent equipment investment repetitive movements , drawing logical protection devices reclosing practices , set up a "charge" counter prepared to vote in every action logic , the " charge" conditions are:
A Not all permitted conditions are met ;
B and more than 10S.
After the above conditions are satisfied for the "charge " full state.
The counter " discharge" conditions:
A either a lockout condition is satisfied;
B or equipment investment action exports.
Any of the above conditions are met, the counter immediately "discharge ."
The following shows a composition prepared by cast action logic diagram :
As can be seen by the figure , prepared to vote every action logic device consists of three parts : Allow conditions lockout condition , charge and discharge logic. Charging and discharging part of the equipment investment means every action is the same logic, which constitutes full compliance with the foregoing conditions on the " charge" , " discharge" requirements and conditions , without the use of the re- configuration.
Therefore, users only need to determine the conditions allow , lockout conditions and related fixed value setting , the corresponding functional configuration backup cast ends. In determining the allowable conditions , latch condition, its constituent elements in the analog input section , each path can be set to a value or less value over action on the digital input , each channel can be set to high or low respectively. effective .
In theory, allow conditions and latch-up condition is a logical "not" relationship of mutual transformation , this point from the above example the figure is easy to see . However, due to equipment investment logic "charge" setting and "discharge" circuit , making conditions determine atresia following principles must be observed : When the device performs a predetermined process equipment investment logic , the result of a previous action should not result in execution of logic follow-up action logic "discharge ." Assume prepare voted device includes A, B and two action logic , a logic execution after its execution results meet B logic operating conditions . When normal operation, should ensure a lockout condition logic does not work , that does not counter the logic "discharge ." Similarly, after a logical action, the conditions should not constitute a B logic " discharge" .
Here are some typical standby power source implementations , other special equipment investment by way of logic diagram programming.

A device to be able to adapt to different requirements, SAI-388D digital standby power source device, graphical interface based programmable logic way to achieve functional equipment investment
Programmable logic equipment investment principles :
SAI-388D digital standby power source device ( hereinafter referred to as the standby switch device ) offers 13 analog inputs , 7 digital inputs , 8 voltage setpoint , six current setpoint , eight time setting , 5 paid to independent contact output. Value and all inputs can be a programmable control equipment investment and action elements . Equipment investment means every action logic control conditions can be divided into two categories: one is allowed to condition , and the other for the lockout condition . When permitted conditions are met, while blocking condition is not met , the equipment investment and exports action . To prevent equipment investment repetitive movements , drawing logical protection devices reclosing practices , set up a "charge" counter prepared to vote in every action logic , the " charge" conditions are:
A Not all permitted conditions are met ;
B and more than 10S.
After the above conditions are satisfied for the "charge " full state.
The counter " discharge" conditions:
A either a lockout condition is satisfied;
B or equipment investment action exports.
Any of the above conditions are met, the counter immediately "discharge ."
The following shows a composition prepared by cast action logic diagram :
As can be seen by the figure , prepared to vote every action logic device consists of three parts : Allow conditions lockout condition , charge and discharge logic. Charging and discharging part of the equipment investment means every action is the same logic, which constitutes full compliance with the foregoing conditions on the " charge" , " discharge" requirements and conditions , without the use of the re- configuration.
Therefore, users only need to determine the conditions allow , lockout conditions and related fixed value setting , the corresponding functional configuration backup cast ends. In determining the allowable conditions , latch condition, its constituent elements in the analog input section , each path can be set to a value or less value over action on the digital input , each channel can be set to high or low respectively. effective .
In theory, allow conditions and latch-up condition is a logical "not" relationship of mutual transformation , this point from the above example the figure is easy to see . However, due to equipment investment logic "charge" setting and "discharge" circuit , making conditions determine atresia following principles must be observed : When the device performs a predetermined process equipment investment logic , the result of a previous action should not result in execution of logic follow-up action logic "discharge ." Assume prepare voted device includes A, B and two action logic , a logic execution after its execution results meet B logic operating conditions . When normal operation, should ensure a lockout condition logic does not work , that does not counter the logic "discharge ." Similarly, after a logical action, the conditions should not constitute a B logic " discharge" .
Here are some typical standby power source implementations , other special equipment investment by way of logic diagram programming.
