“…In the Dutch MV networks, the PQ monitors are installed at the main busbar which is next to the HV/MV transformer-the most optimal location for monitoring voltage dips [12]. Such a system is the so called SASensor system which is implemented in several substations in the Netherlands and results in a significant amount of data acquisition [13]. A simplified network representation of is shown in Figure 1.…”

Voltage dip is considered as the PQ problem related to the highest financial losses for the customers. It occurs unpredictably mainly due to short-circuit faults in the networks. Network operators and customers want to know more about the occurrence and the potential impact of voltage dips. PQ monitoring is an essential tool for the assessment of voltage dips and it can ultimately contribute to the regulation of voltage dip events. In this paper, firstly the methods of voltage monitoring and voltage dips characterization are discussed. Voltage dip indices of six substations are presented in order to assess the occurrence, type and severity of dips that occur in typical Dutch MV networks. Finally, an approach, which is based on the disrupted loads because of a voltage dip event, is introduced and applied to the data at one substation in order to assess the quality of supply voltage and its implications for the end-users.

“…A) Conventional protection relay B) New protection relay Renovating a substation with a conventional system will save initially time, while the organisational structure can be left unchanged. If a choice is made to change the organisational structure and integrate departments to multidisciplinary teams that can cope with all substation functions, the new SAS will cost 25% of a conventional system and reduce time of engineering, maintenance and updating the functions [1]. Within Alliander a Pilot [2] has started in 2004 to implement 10 substations with the SASensor ® system to proof the technology, which has been finalized in 2008.…”

The functions in a substation are increasing. The approach of utilities was to use different boxes per function. With the upcoming of IEC 61850 and increasing processing power, functions are no longer restricted to one box. This new approach of substation automation systems has a great impact on the lifecycle of the system and indirectly on the organisational structure. In the conventional systems each department has its own box. By integrating the functions in one system, the responsibilities of different departments should be clear. Efficient working procedures and smart choices of hardware are proposed to optimize the rollout of new substation automation systems.

The paper presents a probabilistic approach to evaluate the errors due to measurement timescale in medium voltage distribution grid. Three common data acquisition methods by measurement devices are shown, and two kinds of measurement errors due to timescale are defined. Based on Gaussian Process, the stochastic characteristics of household loads are discussed, which are important random variables influencing the grid. A probabilistic approach with Monte Carlo method is presented to evaluate the measurement errors due to timescale problem. Finally, a case study on a simplified grid is given.
